He plagiarized from multiple EDM producers, and then accidentally admitted to it (at least to stealing 'Rebound') http://www.forbes.com/sites/emmawoollacott/2013/04/24/will-i-am-admits-stealing-song-accidentally/ I have no respect for him. He didn't just sample a song without permission, he completely stole a track and put his voice over it. It's a sleazy way to 'make' music. He didn't (and more than likely won't) come out with an apology, but even if he does, the damage has been done. It discredits him even more than previous stolen songs have.
