In a controversy straight out of the files of will.i.am, it seems that Katy Perry's new song "Roar" may have borrowed a little too much from fellow songstress Sara Bareilles' old song "Brave."

will.i.am admits to "borrowing" from EDM DJs Arty and Matt Zo >>

"Brave," written by Bareilles and fun. guitarist Jack Antonoff, is a synth-driven pop song that Bareilles wrote as an empowerment anthem in support of her close friend who was struggling with coming out.

"Roar," written by Perry and friend and collaborator Bonnie McKee, is a synth-driven pop song that Perry wrote as an empowerment anthem in support of herself.

But there's no way, you say. Perry probably didn't know anything about Bareilles' song because she's been too busy in the studio.

Oh, well, except for this tweet:

What other similarities are there? Well, it's the same key, pretty much the same chord progression and the same phrasing.

That certainly doesn't mean it's a rip-off, however. Plus, there are quite a few differences, but don't take our word for it. Below, we have both songs for you to listen to and see what you think.
