Four datasets of music are circulating among artificial intelligence developers, and together they hold more than 21 million recordings, according to a report by The Atlantic. They are filled with copyrighted music, spanning household names and tens of thousands of lesser-known independent artists, according to the report. Two of the datasets each contain more than 100,000 recordings, according to The Atlantic, while the other two are far larger, at roughly 9 million and 12 million tracks.
