Michael Jackson’s Bad turns 25 years old in August, and a special anniversary edition of the album is in the works. A re-release of Jackson’s single “I Just Can’t Stop Loving You” is available now, and it’s backed by a previously unreleased demo titled “Don’t Be Messin’ 'Round.” Naturally, the song leaked onto the Internet nanoseconds after it got an official release, and is streaming in the clip below. It’s not exactly lo-fi, but the song is lacking in the usual ultra-glossy production we’ve come to expect from Jackson. Would this have been issued had the self-styled King of Pop not met an untimely ending in 2009? It seems unlikely, but expect much more of this kind of thing in the coming years.
