The Beatles have won their eighth competitive Grammy award thanks to a little help from artificial intelligence. The 2023 track “Now and Then” — which Billboard reports is the first song knowingly created with AI assistance to earn a Grammy nomination — was awarded Best Rock Performance on Sunday, beating out competition from Green Day, Pearl Jam, The Black Keys, Idles, and St. Vincent.

The track was pieced together using a demo that John Lennon recorded in the late 1970s, with Paul McCartney, Ringo Starr, and George Harrison later providing their own contributions in the mid-‘90s, with the aim of including the final song in The Beatles Anthology project. “Now and Then” wasn’t released, however, due to technical limitations at the time preventing Lennon’s vocals and piano from being separated from the original lo-fi demo.

“To be clear, nothing has been artificially or synthetically created. It’s all real and we all play on it,” McCartney said in 2023, addressing speculation about AI’s role in development. “We cleaned up some existing recordings — a process which has gone on for years.”
