![Spotify and Universal Music strike deal allowing fan-made AI covers and remixes | TechCrunch
Watch out, Suno. Spotify on Thursday announced it has partnered with Universal Music Group (UMG) to allow fans to use generative AI technology to create covers and remixes of their favorite songs. The tool will launch as a paid add-on available only to Spotify’s Premium subscribers and will offer a revenue share with participating artists for the AI-generated music based on their work.
The company did not share pricing or a launch date for the new tool, only that the two companies had come to a licensing agreement. However, Spotify had teased its plans last year, noting that it was working with Universal Music Group, Sony Music Group, Warner Music Group, Merlin, and Believe to develop artist-first AI products.
The AI tools would be created through “upfront agreements, not by asking for forgiveness later,” Spotify said at the time, an obvious swipe at other players in the space, like Suno.
Among the principles Spotify outlined: artists and rightsholders should be able to choose if and how they participate in AI tools, and if they do, they should be fairly compensated.
“Solving hard problems for music is what Spotify does, and fan-made covers and remixes are next. What we’re building is grounded in consent, credit, and compensation for the artists and songwriters that take part,” said Spotify co-CEO Alex Norström, in a statement about the UMG agreement. “Through each technological transformation, we have worked together with Sir Lucian [Chairman & CEO, Universal Music Group] and his team to evolve the music ecosystem into a richer, more beneficial experience for fans and a more rewarding outcome for artists and songwriters.”
UMG Chairman and CEO Sir Lucian Grainge, meanwhile, touted the development as a way for artists to deepen their fan relationships while also creating additional revenue opportunities. There’s no word yet on which UMG artists have agreed to participate.
While services like Suno and Udio have been pioneers in the AI music space, they moved forward on shaky legal ground when building their AI music-making tools. Unsurprisingly, the major labels quickly sued. In November, Suno ended up settling a 0 million lawsuit with Warner Music Group, which came shortly after Universal Music Group (UMG) had settled its own suit with Udio.
Today, Suno is still facing copyright claims from UMG and Sony Music, among others. Udio, meanwhile, has settled with Warner Music and UMG, but is still working to settle with Sony.
Seeing demand for this type of activity from consumers, Spotify went straight to the labels for a deal of its own. UMG may be the first of many label partnerships to come, though the company didn’t outright say so.
The news was shared amid a slew of Investor Day announcements from Spotify on Thursday, which also included an AI-powered audiobook creation tool, AI-powered features for podcasters, a desktop app to produce personal podcasts via AI, and reserved concert tickets for top fans.

A former engineer at Elon Musk’s xAI has filed suit against the company and its parent SpaceX claiming he was fired for raising concerns about AI safety.
Devin Kim, who left xAI in September 2025, filed the suit in a California state court on Tuesday. The complaint comes days before SpaceX is set to join the public markets in what’s shaping up to be the largest IPO in history.
According to the lawsuit, which TechCrunch has viewed, Kim became a prominent voice for AI safety while working on Grok, xAI’s AI chatbot. He allegedly complained repeatedly about xAI’s failure to prioritize safety in Grok’s development, a product that has since come under fire for a range of safety and behavioral issues. In particular, Kim was concerned with the possibility that Grok could foment discrimination and help spread information about weapons of mass destruction.
“Grok, of course, proved Mr. Kim right by engaging in spectacular displays of online hatred and vitriol, with the model likening itself to Hitler (‘MechaHitler’),” the lawsuit reads. “Following the Hitler debacle, Mr. Kim worked to re-evaluate Grok’s political bias and discriminatory tendencies.”
September was my last month at xAI! I joined as one of the first members of the post-training team in 2024 and eventually led research tooling, where we built some of the world’s best systems to accelerate Grok’s development.On my first day, I was at the whiteboard with @ibab…— Devin Kim (@devindkim) October 3, 2025
A few months after Kim departed xAI, Grok made headlines again when the chatbot was used to flood X — Musk’s social media platform that also falls under the xAI umbrella — with nonconsensual sexual imagery.
The lawsuit also positions Kim as a whistleblower who was concerned about xAI’s alleged disregard for AI safety as “unlawful” in areas such as internet regulation, consumer protection and unfair business practices, and arms and explosives regulation, among others.
xAI and SpaceX did not immediately respond to requests for comment.
Kim’s focus on AI safety predates his time at xAI. While working at Scale AI, Kim worked on early safety AI initiatives, like leading a project that produced training data for AI to train systems to detect harmful content and comply with governance policies. Last week, the nonprofit Center for AI Safety, which focuses on AI risks, named Kim as its president.
Interestingly, the lawsuit doesn’t implicate Musk himself as a reason for a lack of safety. Rather, Kim’s lawyers describe Musk as having directed xAI to follow the law and implement appropriate safety and testing processes. Instead the claim targets Kim’s supervisor, xAI co-founder Jimmy Ba — who left the company earlier this year — saying that Ba ignored Musk’s directives and retaliated against Kim for pushing for safeguards, in an effort to “silence his repeated complaints about AI safety and biases.”
The lawsuit portrays Ba as someone who vehemently opposed AI safety measures, allegedly telling Kim at one point “AI will kill us all anyway,” and who was instead driven by a mission to make xAI the first to reach superintelligence.
“In one instance in or around August 2025, Mr. Ba attempted to thwart EU safety regulations during the release of Grok Code 1, misrepresenting aspects of the model in order to avoid legally required testing,” the complaint says. “Mr. Ba indicated that he would rather release an unsafe model than a poor-performing one. Mr. Musk ultimately had to intervene.”
According to the lawsuit, Kim intended to give a presentation of his findings the week of September 15, 2025, but Ba called him into a meeting and told him they should “go [their] separate ways” without providing a satisfactory reason.
TechCrunch has reached out to Ba for comment.
Kim is seeking compensatory and punitive damages, as well as a declaratory judgment that xAI and SpaceX’s conduct was unlawful.

![Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica
The East Antarctic Ice Sheet is almost unfathomably huge. Covering about 75% of the entire frigid continent (nearly everything on its side of the Transantarctic Mountains), the sheet covers about 3.9 million square miles (10.2 million square kilometers) and extends down 1.4 miles (2.2 km), on average, before coming into contact with Earth’s surface. At its deepest, the ice plunges down over 3 miles (4.9 km). For decades, scientists assumed that this literally continent-sized block of ice rested on an expansive and stable chunk of Earth’s crust known as a craton. A team of researchers has now complicated that picture—mapping a vast, interconnected geological structure that fans out from a troubling “tectonic deformation.” Beneath this ice sheet, thinner and more geologically recent slices of crusty lithosphere fan out into hidden valleys called “pull-apart basins.” These basins—30 elongated wedge-shaped valleys in total—constitute an entirely new, continental-scale geological region underneath Antarctica, in fact, one which the researchers have named the East Antarctic Fan-Shaped Basin Province (EAFBP). But it’s how they likely formed that has now caught researchers’ attention.
To put it bluntly, it turns out that about 90% of the planet’s fresh water ice may not be on solid ground. Geologist John Goodge called the team’s findings “provocative” in an independent commentary on the new study, published Thursday in the journal Nature Geoscience.
“East Antarctica is typically considered from seismic tomography and geodetics to be ancient and generally stable,” according to Goodge, who studies continental tectonics with the nonprofit Planetary Science Institute. “[But] something else is going on at depth.” Continental divides Goodge speculates that this seemingly “coherent pull-apart system,” as presented in the new study, might help explain a variety of mysterious heat and water flows beneath this ice sheet’s surface, like that enormous subglacial lake identified in 2016 or some of the hundreds more like it.
The study’s authors, led by geophysicist Egidio Armadillo at the University of Genoa in Italy, agreed: “Because these basins underlie about half of the East Antarctic Ice Sheet, they are likely to heavily influence both ice-flow and landscape evolution,” the researchers wrote in their study, also published Thursday in Nature Geoscience. Armadillo’s team, coordinating across Europe and the U.K., developed their new understanding of Antarctica’s hidden bedrock via an exhaustive set of sensory data. Gravitational and magnetic anomalies were mapped via low-altitude airborne surveys. Ground surface features were mapped with seismic tools, using sound waves that vibrate through the ice and ping back information about subglacial landscapes in 3D. The grey, magenta, and cyan lines represent the apparent new fault lines discovered. Credit: Nature Geoscience All of this data—the fruits of “multi-national efforts to image within and below the ice sheet,” as Goodge put it—had already revealed that regions of the continent were “undergoing more rapid movement and ice-mass loss than previously recognized.” Armadillo’s team merely helped to explain why.
The mechanism Armadillo and his colleagues proposed for the formation of these fan-shaped basins is called “distributed rotational extension.” It involves points called Euler poles around which tectonic plates pivot or rotate rather than smash into each other or pull apart. The result is a bit like decks of cards being spread out on a table, thinning out the stack of Earth’s crust as it moves. An icy situation Goodge took pains to spell out the basins’ implications for melting Antarctic ice due to climate change and the risk of rising global sea levels.
The mere existence of these basins, he wrote, “could introduce widespread, systemic instability to the East Antarctic Ice Sheet” via thinner layers of Earth’s crust and more heat flow from below. On top of that, a series of fault-line “troughs” documented between the basins appear “tailor-made to promote outward flow of ice streams from the interior” into the world’s oceans, he said. That said, the team’s findings are unlikely to end this debate. As Goodge noted, Antarctica is “the last continental frontier of scientific exploration.” It’s still a very mysterious place, one that’s challenging to study given its inhospitable temperatures and extreme geography. Its “cryptic subglacial geology” might stay that way for a while. #Scientists #ContinentSized #Geological #Structure #Hiding #Beneath #AntarcticaAntarctica,Geology,mapping,Plate tectonics](https://gizmodo.com/app/uploads/2026/06/East-Antarctic-Fan-shaped-Basin-Province.jpeg "Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica

A team of researchers has now complicated that picture—mapping a vast, interconnected geological structure that fans out from a troubling “tectonic deformation.” Beneath this ice sheet, thinner and more geologically recent slices of crusty lithosphere fan out into hidden valleys called “pull-apart basins.” These basins—30 elongated wedge-shaped valleys in total—constitute an entirely new, continental-scale geological region underneath Antarctica, in fact, one which the researchers have named the East Antarctic Fan-Shaped Basin Province (EAFBP). But it’s how they likely formed that has now caught researchers’ attention.
To put it bluntly, it turns out that about 90% of the planet’s fresh water ice may not be on solid ground. Geologist John Goodge called the team’s findings “provocative” in an independent commentary on the new study, published Thursday in the journal Nature Geoscience.
“East Antarctica is typically considered from seismic tomography and geodetics to be ancient and generally stable,” according to Goodge, who studies continental tectonics with the nonprofit Planetary Science Institute. “[But] something else is going on at depth.” Continental divides Goodge speculates that this seemingly “coherent pull-apart system,” as presented in the new study, might help explain a variety of mysterious heat and water flows beneath this ice sheet’s surface, like that enormous subglacial lake identified in 2016 or some of the hundreds more like it.
The study’s authors, led by geophysicist Egidio Armadillo at the University of Genoa in Italy, agreed: “Because these basins underlie about half of the East Antarctic Ice Sheet, they are likely to heavily influence both ice-flow and landscape evolution,” the researchers wrote in their study, also published Thursday in Nature Geoscience. Armadillo’s team, coordinating across Europe and the U.K., developed their new understanding of Antarctica’s hidden bedrock via an exhaustive set of sensory data. Gravitational and magnetic anomalies were mapped via low-altitude airborne surveys. Ground surface features were mapped with seismic tools, using sound waves that vibrate through the ice and ping back information about subglacial landscapes in 3D. The grey, magenta, and cyan lines represent the apparent new fault lines discovered.

The mechanism Armadillo and his colleagues proposed for the formation of these fan-shaped basins is called “distributed rotational extension.” It involves points called Euler poles around which tectonic plates pivot or rotate rather than smash into each other or pull apart. The result is a bit like decks of cards being spread out on a table, thinning out the stack of Earth’s crust as it moves. An icy situation Goodge took pains to spell out the basins’ implications for melting Antarctic ice due to climate change and the risk of rising global sea levels.
The mere existence of these basins, he wrote, “could introduce widespread, systemic instability to the East Antarctic Ice Sheet” via thinner layers of Earth’s crust and more heat flow from below. On top of that, a series of fault-line “troughs” documented between the basins appear “tailor-made to promote outward flow of ice streams from the interior” into the world’s oceans, he said. That said, the team’s findings are unlikely to end this debate. As Goodge noted, Antarctica is “the last continental frontier of scientific exploration.” It’s still a very mysterious place, one that’s challenging to study given its inhospitable temperatures and extreme geography. Its “cryptic subglacial geology” might stay that way for a while. #Scientists #ContinentSized #Geological #Structure #Hiding #Beneath #AntarcticaAntarctica,Geology,mapping,Plate tectonics")
