It was followed by the release of her debut album, Thankful (2003), which debuted atop the US Billboard 200.

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.
