"Down" is the third single from Blink-182's 2003 self-titled album. It is the band's tenth song to reach the top 10 on the chart. It has also been released as a downloadable track for the Rock Band video game.
According to Tom DeLonge in the liner notes of the album, the song came from a picture he had in his head about a girl and a boy in a car with it raining outside (hence the "Down, Down, Down, Down" chorus) and how much the boy wants to kiss her and make her stay (another reason many suspect for the chorus).
An alternate arrangement of the song is available on the "Part 2" single, called the "T.L.A. Arrangement", which was done by the song's mixerTom Lord-Alge. It is slightly different, featuring an extended ending where Mark Hoppus's vocals are sung over the main chorus instrumental. Also the main guitarriff is panned completely to the left as opposed to it having a small presence at the right on the main version.
The music video features aerial footage of Los Angeles and the band attending a backyard party. A police officer, played by actor Terry Crews, enters the party in search of a gang member, who escapes, and whom the officer pursues. At one point in the video, Crews clearly mouths the word "fuck" as the gang member escapes over the wall.
