Caught Up - The Fall of Troy

Doornails - NOFX

California Waiting (I prefer the version from Holy Roller Novacain ep) - Kings of Leon

Lots of Zeppelin sounds great when played on an acoustic

My Curse - Killswitch Engage

Swing Life Away - Rise Against

Story of my Life, and Ball and Chain - Social Distortion

Not all of these are clean but they all sound good played on an acoustic
