From Wikipedia
In
North America (and some countries elsewhere) the opening theme of the series is "
Teardrop" by
Massive Attack. "Teardrop" has lyrics, sung by guest vocalist
Elizabeth Fraser of
Cocteau Twins; however, the version used in the opening credits uses only the beginning and ending sections, which are solely instrumental. Due to rights and licensing issues, in most countries a piece of music named "House End Credits" is used, which was composed specifically for the show by Jon Ehrlich, Jason Derlatka, and Leigh Roberts. With the second season, this was replaced with a similar track by only Ehrlich and Roberts. This theme tune, however, is only used in the televised broadcast. In the DVD release (Season 2), the original (American) theme is used. In
Italy, opening themes for season 1–2 and season 3 are switched, so that the original "Teardrop" is used for season 3, while both Season 1 and 2 use the edited version. In season 4,
Australia began using "Teardrop" as the opening theme, replacing the specifically composed "House" theme. The satirical
British television show
Dead Ringers, which sometimes spoofs
House, uses "Teardrop" for the spoof's opening theme. "Teardrop" is also used in the season 2 region 2 and region 4 release, replacing the "House" theme at the beginning of the episode.
