Jackson Estate, Sony Pulling Leaked Track

Every Michael Jackson fan was overjoyed at the new song that leaked this weekend -- everyone except his record label, Lenny Kravitz and all of Michael's lawyers.

Sources tell TMZ the Jackson song, called "Another Day" and done with Lenny Kravitz, was never meant to see the light of day. We're told Sony, with the support of Jackson's estate lawyers, wants to have the song pulled off the Internet.

For his part, Lenny Kravitz posted a video saying he didn't leak the song and he has no idea how it got out there.

He says the song is not mixed and not a final version.
