Guilty as charged. Earlier today (April 23), will.i.am called into Los Angeles station KIIS and admitted to jacking the beat to dance artists Arty & Mat Zo's song "Rebound" for his recent single "Let's Go," featuring Chris Brown. Arty had previously tweeted about the similarities between the two songs. Will told KIIS that he thought that he had obtained permission to use "Rebound." "I'm a fan of Arty," Will told KIIS. "I think he's great and the world needs to know about how talented those guys are. It's sad that it's turned into a fiasco but hopefully it's resolved because I'm a fan of those guys to the point where I wrote to their instrumental. We're fixing it now." Unfortunately, claims of plagiarism are all too common in the music world. Read on to check out other music stars who've been accused of stealing songs.
