(The Hardest Ever)” off will’s album #willpower. Will says, “You play your music and the first thing someone says, ‘Who’s gonna be on it? So I think of the hardest thing ever. And it happened, Mick Jagger.” The Black Eyed Peas man explained that Interscope chairman Jimmy Iovine, who always wanted to work with Jagger, made the collaboration happen, and even decided to produce the track. #willpower is out next year.
