Here we are - Breaking Benjamin
Unknown Soldier - Breaking Benjamin
Breath - Breaking Benjamin
Weight of the World - Saliva
Killswitch Engage - Arms of Sorrow

But I sometimes prefer to songs that'll psyche me up when im depressed, its like saying 'Yea, this world sucks, but I aint gonna give in to it'. In which case it would be:

3 6 Mafia - Its a fight
Eminem - Til I Collapse
Eminem - Lose Yourself
Tupac - I'm Alive
DJ Green Lantern - Fight Song
