Sæglópur
"Sæglópur" ( Icelandic for "lost at sea" or "lost seafarer") is a song by Sigur Rós, released in 2006 as a single from the 2005 album Takk.... Parts of the song are in Icelandic, although a lengthy portion is in Hopelandic, a "language" of nonsense words selected by the band that sound similar to Icelandic.
