Heathens. It's a
bloody awful song. Good Charlotte are a nasty, foul-smelling, crusty splatter of a stain on "alternative" music. They're supposedly "punk" but have no ****ing idea what punk even
is. Go and listen to some Bad Religion.
That's ****ing punk.

Anyhoo - anon - you really won't get very good without some lessons of some sort. You can learn all the chord shapes and scales in the world, but you need to have someone with experience who can tell you how to do stuff, what you're doing well and what you're doing badly. Even if you just know someone else who plays, get 'em to help you. You'll improve much faster that way...
