New Beatles Song "Now and Then" on Track for UK No. 1, Technology Could Allow More Songs in the Future

An AI-based technology utilized by filmmaker Peter Jackson allowed the Beatles' unfinished track "Now and Then" to be released, sparking discussions about creating more Beatles songs from unused material despite McCartney stating this is the last Beatles song.

The new Beatles song, 'Now and Then', created from an unfinished John Lennon demo with the use of technology, is on track to become the band's 18th number-one song on the U.K. charts.
Filmmaker Peter Jackson's AI-based technology was used to separate out voices and sounds from the Lennon demo, enabling its transformation into the final song.
The song features contributions from all four Beatles members - Paul McCartney, Ringo Starr, and posthumous inputs from John Lennon and George Harrison.
Despite Paul McCartney's statement that this is the final-ever (new) Beatles song, Jackson suggests that it is possible to create more songs from the raw material he has access to, using machine learning technology.
The Beatles' 'Now and Then' was released as part of a global rollout on November 2 and included a documentary about the making of the song, available exclusively on Disney+.
Despite ethical concerns around the technology in the music community, McCartney stated that the use of AI to complete 'Now and Then' was about embracing new technology, consistent with the Beatles' creative approach towards their work.
