*Producers of a new album featuring never-before-released Michael Jackson songs will include a track recorded with soulful rocker Lenny Kravitz, reports Contact Music.

The song, titled “Another Day,” was originally tapped for Jackson’s 2001 CD “Invincible,” but it didn’t make the cut because MJ felt it was “too rocky.”

According to Contact Music, producers have now decided it’s the best unreleased tune from the King of Pop’s recent back catalog, and will include it on the first album of new Jackson material since his death in June.

“It’s really about how his life has been so incredible, and, without God, it wouldn’t be so,” Kravitz said of the song.

Meanwhile, the artist says he’ll never forget his experience with Jackson in the studio.

“It was a blessing… I got to work with this cat and we had so much fun,” he said. “We laughed all day long; he’s a funny, funny dude, and the work ethic was serious… We had a lot of respect for each other. It’s a beautiful memory.
