In its four seasons, "Gossip Girl" music has been some of the best TV soundtrack music on the tube. In many cases, this music was by unknown artists that went on to become big stars. In some instances, however, the performers of these songs have stayed relatively obscure. Whatever the case, the music is wonderful. If you bought a lot of the songs you heard on the show, chances are you've got a pretty good iTunes collection.

"Young Folks" by Peter Bjorn and John

This is one of the best pop songs to feature whistling in a long time. It is performed by the Swedish trio, Peter Bjorn and John, and appeared as music in season one of "Gossip Girl."

"Believe" by The Bravery

This spiritually-themed song was also featured music in season one of "Gossip Girl." The lyrics find the character in the song searching for something or someone to believe in. This is an area most people find themselves in at one time or another.

"Moon River" by Henry Mancini

This was not the first time Henry Mancini's "Moon River" made it onto a soundtrack. The song was first made famous sung by Audrey Hepburn in the '60s film "Breakfast At Tiffany's." Pop singer Morrissey also recorded a wonderful version of this song with its beguiling melody. However, the song also made it onto the first season's music for "Gossip Girl."

"Papparazzi" by Lady Gaga

When Lady Gaga's "Papparazzi" popped up in the music mix for the second season of "Gossip Girl," the world was not yet gaga over the lady. They would soon fall in love with her, however, the way a photographer falls for a celebrity.

"Lisztomania" by Phoenix

Phoenix's hit, "Listomania" made it onto the list of season three "Gossip Girl" songs. This was "Gossip Girl" music with a distinctly French accent.
