'What I've Done' was released by Linkin Park in 2007 as the lead single from Minutes to Midnight and featured over the end credits of Transformers. Its themes of regret and starting again made the chorus widely recognised beyond rock audiences. Online, editors isolated and stretched the title line, turning a sincere moment into a joke about guilt and bad decisions. Like hello darkness my old friend, it became shorthand for dramatic remorse, and the elongated version still circulates in meme edits, gaming videos and reaction compilations.
