An 90's Australian group of the same name can be seen at http://www.last.fm/music/PoP
Pop! were a UK pop group consisting of members Glenn Ball, Hannah Lewis, Jaime Tinkler, and Jade McGuire. The pop group was formed in 2004 when they were signed by Pete Waterman. They released three singles under the Sony/BMG record label and disbanded in early 2005 after not achieving optimal chart positions and Jade McGuire's pregnancy.
In March 2006, Glenn Ball, a former member of the group leaked a snippet of a song entitled Don't let it go to your head on his official website. It was a track meant to be a part of their unreleased album.
The fictional band PoP from the movie Music & Lyrics have their own Last.fm page.
