"Unintended" is a single by the English rock band Muse from their debut album, Showbiz. It was the fifth single that the band released. The release date in the UK was 30 May 2000, and was released as a two-CD set and an accompanying 7" vinyl. The song also appears on the Hullabaloo Live DVD and on HAARP. Its guitar track is very similar to "If" by Pink Floyd from their album Atom Heart Mother. When originally played live, bassist Chris Wolstenholme would play the guitar part on either an electro-acoustic or electric guitar, and play the bass part simultaneously using a Roland PK-5 floor based pedal, while Matt Bellamy improvised noises on the electric guitar. Although the song was retired from most live sets in the Absolution era, it has been played at a few recent shows, including the shows for the live album HAARP. It features Bellamy playing guitar and Wolstenholme playing bass.
This song has been covered by The Rasmus live. Lead singer Lauri Ylönen is known to be a fan of the band.
It has also been covered in a capella by the Latvian group Cosmos.
