Google has revealed an experimental AI tool, Dream Track, that creates original songs in the style of selected famous singers. It is among several new developments announced Thursday by the tech giant at the intersection of music and AI.

In a demo of Dream Track, a user simply types in a prompt — in this case, "a ballad about how opposites attract, upbeat acoustic" — and the system spits out this short clip of a new song, sung by pop star Charlie Puth's voice clone with a stylistically relevant backing track.

Eight other artists including Alec Benjamin, Charli XCX, Demi Lovato, John Legend, Papoose, Sia, T-Pain, and Troye Sivan signed on to participate in Google's project. In another demo video, the typed prompt "A sunny morning in Florida, R&B" yields a song performed in suitably auto-tuned fashion by a synthesized T-Pain.
