'Love Song' hitmaker Sara Bareilles has opened up about the similarities Katy Perry's new single 'Roar' has to her own track 'Brave' and revealed that it's driving sales of her song so there's an upside. 

Internet users noticed that 'Roar' sounded very much like the track shortly after it debuted and it became a talking point among online fan communities, but Bareilles has now given her opinion on the situation. 

Speaking to Billboard, she explained that she doesn't believe Perry has 'stolen' material from her or plagiarised in any way: "I was stoked. I was like, 'Great,'... I was like, 'You guys want to go get (mad) about something and buy my music, that's great.'"

"I don't feel like anything was taken from me artistically. I wasn't the one having any problems with it. I've known Katy a long time. We are friends and she and I spoke about it. I look at it as two female artists who are releasing a message of empowerment."

She added that seeing the tension between her fans and Perry's was "disappointing": "To be totally honest, I was sort of disappointed in how aggressive fans were being about it. I don't promote drama in my life and competition and stuff like that."
