I think it’s because that was when it was originally remixed but the two camps (DG and RW) have been in dispute over its release since! I may be wrong but that’s what I thought I read last year.
Edit:Just found this to confirm my original comment.
As the title suggests, the remix was completed in 2018 and originally intended for release around that time; however, the reissue was delayed as former band mates Roger Waters — who largely penned the album himself, with the exception of “Dogs” — and David Gilmour sparred over liner notes that were intended to accompany the reissue.
Only The Strong Survive is the new album from Bruce Springsteen, and his first new studio album since 2020’s Letter To You. The album is a collection of soul music gems, that celebrate the legendary songbooks of Gamble and Huff, Motown, Stax and many more.
Only The Strong Survive features vocals from Springsteen and instrumentation primarily from his longtime producer Ron Aniello. The album also features guest vocals from Sam Moore, as well as contributions from The E Street Horns, full string arrangements by Rob Mathes and backing vocals from Soozie Tyrell, Lisa Lowell, Michelle Moore, Curtis King Jr., Fonzi Thornton and Dennis Collins.
