as the album Demolicious by Green Day. Other demo versions have been unofficially released as bootleg recordings, such as The Beatles' bootleg demos and the Beach Boys' Sea of Tunes series. Several artists have eventually made official releases of demo versions of their songs as albums or companion pieces to albums, such as Florence and the Machine ("What the Water Gave Me", among others) and Cults on the EP Sunday Jams. The event of a demo tape appearing on eBay has happened in the past, with the recordings being leaked onto the internet. In rare instances, a demo may end up as the final released recording of a song, as was the case with Foster the People's "Pumped Up Kicks". The version of "Pumped Up Kicks" that was released as a single and subsequently became a hit was a demo recorded by frontman Mark Foster alone, before he had formed the group. In 1982, Bruce Springsteen recorded ten demo songs in his bedroom that he intended to later record with his E Street Band, but he subsequently decided that he preferred the acoustic demos and released them as the 1982 album Nebraska. In more underground forms of music, such as noise music, black metal, or punk rock, demos are often distributed by bands to fans as self-releases or sold at a very low price. Amateur (and some professional) musicians may choose to make demos available to interested listeners through websites such as SoundCloud or Bandcamp in order to share new ideas, receive feedback and/or provide fans with "behind the scenes" access to the songwriting process.
