NEW YORK (AP) A new Michael Jackson album is expected by the end of the year, culled from unreleased material in his vaults. But Jackson collaborator and Black Eyed Peas frontman will.i.am is vehemently opposed to the idea.

"I don't think that should ever come out. That's bad," he said. "He was a perfectionist and he wouldn't have wanted it that way. How you gonna release Michael Jackson when Michael Jackson ain't here to bless it?"

Will.i.am collaborated with Jackson on the rerelease of "Thriller" in 2008 with remixed versions of some of the album's classic songs. He said Jackson was very particular about all aspects of his musical productions, from his vocals to arrangements to instrumentation.

"Now that he is not part of the process, what are they doing? Why would you put a record out like that? Because he was a friend of mine, I just think that's disrespectful," he said. "What's wrong with what he already contributed to the world?"

The Jackson estate did not respond to a request for comment.

When asked about the high demand for any new Jackson music, will.i.am replied: "So what? You don't disrespect someone when they're gone. ... How much can you suck from his energy? ... Freaking parasites!"

Not much is known about what will be on the album, but Michael's brother Jackie has said he and brother Marlon were working on the record with John McClain, Jackson's former manager and executor of his estate.
