Katy Perry’s new single Roar leaked two days early. Roar is written by Katy, Bonnie McKee and Henry Walter and produced by Dr Luke, Max Martin and Cirkut. It’s a progression from Katy’s previous album Teenage Dream as it’s not as colourful but at the same time it’s not as dark as expected.

There’s been plenty of comparisons online of Roar and Sara Bareilles’ song Brave, but while there are similarities, Roar has a lot of differences that make it more anthemic.

The lyric video for Roar is also very creative, using Whatsapp and Emoji icons to display the lyrics. Check it out below:

Roar is available worldwide on iTunes.
