I prefer Punk Rock and Alternative
Bands like: Blink-182, Sum41, Good Charlotte, Some Simple Plan, Yellowcard, A Change of Pace, BoxCar Racer (not punk), All American Rejects, Anberlin (not punk), American Hi-Fi, Bowling for Soup, Jack's Mannequin (not punk), Fountains of Wayne (Stacy's mom), Wheatus (teenage dirtbag), MGMT (not punk).
That's just a list i could think of.
I'll make a thread later.
