This week Katy Perry officially released her first single, “Roar” to her new album, Prism, which is due out October 22nd. To add to the hype, a video was produced showing the pop star going about her day while text messaging in a thread on an iPhone using emoticons to state the lyrics to her song.

Now other musicians have come forward accusing Perry of ripping off their ideas.

First up was Sara Bareilles who’s recently released album features the single “Brave,” which came out 4 month prior to the the album drop. Bareilles, along side hundreds of online fans, have done a side-by-side comparison of the two songs.

Take a look and listen to the originals:

Last weekend Bareilles gave her response by simply tweeting (@SaraBareilles) “All love, everybody. All love.”

Then earlier this week Dillon Francis accused Perry of plagiarism on her video. Francis stated he came up with the idea of text messaging the lyrics of his song, “Messages”, while the song is heard on the video.

Dillon tweeted, “Damn first @official_flo steals @diplo’s “butters theme” music idea now @katyperry steals my “messages” music video idea..What the f**k?”

However, Francis went on to say that, “Legitimately this is so dope that @katyperry’s director thought my video was good enough to rip off.”

In other Katy Perry news, she will be performing her song “Roar” at the MTV’s Video Music Awards at the Barclays Center in Brooklyn on Aug. 25th. Maybe she’ll bring Sara and Dillon on stage with her…
