Cliffs Of Dover. If I want to hear something get butchered I'll go to the deli.
Any tuning with the low E tuned down sooo low that only whales can hear it.
If you're an old guy with Khaki shorts on don't play any Tom Petty. You're going to play it at your pool side gig anyway, why play it on your day off?
Any Limp Bizquick. They sucked 15 years ago and suck worse now. Don't suck like them.
Any Black Sabbath. Iommi was missing fingers..........are you making fun of the disabled?
Any songs that reference guns. Think of the Liberal hipsters and their feelings?
