Angels and Airwaves "The Gift" featured on Gossip Girl Pilot Episode is one great tune and I recommend you listen to the entire album!
Gym Class Heroes "The Queen and I " featured on Gossip Girl Episode titled : The Wild Brunch. I wasn't really interested in this band because of their name, but I have to admit these guys are really good!
Sea Wolf's "You're a Wolf" featured on Gossip Girl Episode titled "High Society" is one great tune...and play regularly on INDIE 103.1 but you can also get it from Amazon!
