Let’s take a break from ruining your ‘90s alternative faves and switch back to hip-hop for a second. When it comes to plagiarism, hip-hop music is different since it's a genre that mostly relies on sampling, which is completely legal. Good artists can turn an old sample into something new and different — and then you have people like Will.i.am. 

The Black Eyed Peas member and producer has been accused of plagiarism so many times, I honestly don't even know where to start. But for now, let's just focus on the only song he actually admitted to "accidentally" stealing. His track "Let's Go" is pretty much just DJ Arty's track "Rebound" with obnoxious rapping on top. Fans were furious and called him a "thief" when the song dropped. 

"Arty is a dope producer so I wrote this song to 'Rebound' this last year," he admitted in 2013. "I got in touch with Arty and showed it to him, did a different version to it 'cause I asked him [to] make it newer 'cause I don't just wanna take your song and rap over it."

Except that's exactly what he did?! In the past, Will.i.am has also been accused of plagiarizing tracks like Black Eyed Peas' "Boom Boom Pow" and "I Gotta Feeling," but both those suits were thrown out in court. He’s also been accused of ripping off artists when producing music for other people. Fergie’s “Fergalicious," for example, sounds awfully similar to J.J. Fad's “Supersonic.”
