"Hoppípolla", Icelandic for "Jumping into puddles") is a song by Icelandic band Sigur Rós from their 2005 album Takk.... It was released as the album's second single on November 28, 2005. The lyrics are mainly in Icelandic, with some nonsensical phrases, a "language" the band calls Vonlenska ("Hopelandic"). As with many of the band's songs, it was given a nickname in the early stages of writing. Hoppípolla was "The Money Song", as the band was certain they had written a song which would have commercial success. It is the band's most successful single, charting at #24 on the UK Singles Chart in May 2006 due to the song's increased popularity as the theme for the BBC's Planet Earth. The single also features "Með blóðnasir", an instrumental coda to "Hoppípolla", which is also featured on Takk...; and a studio remake of "Hafssól", a song previously released on the band's 1997 debut album, Von. The title appears as "Hafsól" on the single.
