Underdog is the sixth album released by Audio Adrenaline.

Underdog was the second single released off the dubut Testeagles album Non Comprehendus.

"Underdog" is a song from Rock Star Supernova's debut album. It is track 6 on the album, and though it was never performed on the television series Rock Star: Supernova, many fans may recognise the song the be the music the final 15 rockers were challenged to pen lyrics for in the very first reality episode. The lyrics however, are radically different to any submission made by the finalists.
