"Since U Been Gone" is a song recorded by American singer Kelly Clarkson from her second studio album, Breakaway (2004). The song, which was 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. It is an uptempo pop rock and power pop power ballad that infuses electronic sounds with a mixture of a soft and loud pop rock sound. 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.
"Since U Been Gone" received positive reviews from music critics who considered the song to be the highlight of Breakaway. Critics also felt that it was one of the best pop songs in the last decade. Rolling Stone ranked it at number 482 of the 500 Greatest Songs of All Time in 2010 and at number 93 in the revamped 2021 ranking. "Since U Been Gone" was a commercial success. In the United States, the song peaked at number two on the Billboard Hot 100, behind "Candy Shop" by 50 Cent and Olivia. It topped the US Pop 100 for six consecutive weeks and the US Pop Songs for seven consecutive weeks respectively. It was certified platinum by the Recording Industry Association of America (RIAA) for shipments of over one million copies sold. "Since U Been Gone" was also a worldwide success, peaking in the top five in Austria, Australia, Ireland, the Netherlands, and the United Kingdom.
