Yeah, Wal-Mart's god-awful. Other people already gave the reasons why, so I won't list them again. Put some good hardcore punk in the videos, it's make you seem less "poseur" (even though trying to not be poseur is pretty poseur, it'll work-trust me.) Put in some Dead Kennedys, Sex Pistols, Clash, Gang Green, Orange Goblin, or some newer punk, like Bad Religion or NOFX. Stay away from big corporate bands like Linkin Park, MCR, Good Charlotte, etc.
