"Since U Been Gone" is a song recorded by American singer Kelly Clarkson from her second studio album, Breakaway (2004). The song, written and produced by Max Martin and Lukasz "Dr. Luke" Gottwald, was released as the lead single from Breakaway two weeks before the album was released. An uptempo power ballad with alternative rock and indie rock influences, it mixes loud and soft pop rock, power pop, bubblegum, and pop-punk with electronic sounds. Martin originally wrote "Since U Been Gone" with Pink in mind, but she turned it down. It was then given to Hilary Duff, but she rejected the song because she could not reach its higher notes. The song was finally given to Clarkson after Clive Davis convinced the writers to give it to her. Clarkson decided to add heavier guitars and harder drums to the song after noticing that the demo had an obvious pop sound. Lyrically, the song is written from a woman's point of view where she expresses her sense of relief with the end of her troubled relationship.
