The lyrics of the song deal with the use of club drugs such as MDMA and Ketamine in nightclubs and parties. The song deals with the effects of such drugs on the human body through the eyes of a user, who asks, "Is it so wrong, to want rewarding?/To want more than is given to you?".
A video for the song was released on 5 December 2006, and was directed by Walter Stern, also known for directing videos by Massive Attack, The Prodigy and most notably the The Verve's "Bitter Sweet Symphony". In the video, all members of Bloc Party are at a nightclub (which, in reality, is Café 1001, Dray Walk, Truman Brewery, London). It follows them throughout the night even though they do not appear to be doing much. Okereke is the only one who actually gets up and goes around. The other members just sit around while Okereke goes off on his own journey, whilst cigarette burn effects and other visual distortions appear.
