Pop rock/hip-hop hybrid group Gym Class Heroes were an unlikely pick as one of the next indie bands to break into pop and alternative radio, but once "Cupid's Chokehold" hit in 2005 and again in 2006 as a re-release, it seemed their passports were stamped for a respectable level of stardom. After rumors of a possible breakup in 2010, the band returned in full force and are set to deliver their new album, "Papercut Chronicles II," Nov. 15.
