this is a song played in a LOT of mtv shows, usually at the end of shows like "date my mom" or something where they're running off into the distance. it's just a guitar riff and it only gets played for a few seconds.
it was played in the hills season 3 episode 14 "forgive and forget"
the time was -4:06 online, where audrina and her friend are talking at the jimmy kimmel show right after sean kingston plays. the scene goes into a shot of the teen vogue offices the night after heidi sees lauren . please help me! i cant stand not knowing this song! mtv plays it in their shows all the time!!!!!
