Kelly Clarkson’s “Since U Been Gone” (2004) is a pop-rock powerhouse that became an anthem for post-breakup empowerment. Written by Max Martin and Dr. Luke, the song famously pairs a quiet, tension-building verse with an explosive, guitar-driven chorus that let Clarkson’s vocals soar. Peaking at No. 2 on the Hot 100, it earned critical acclaim for bridging pop and rock and won a Grammy. More importantly, it turned into a generation-defining song — the kind you can’t help but belt out at the top of your lungs — as Clarkson’s cathartic release of “since you been gone, I can breathe for the first time” spoke to anyone finding strength after a breakup.
