So im sort of a punk-goth(dark clothes, spiked wrist bands, etc, etc.) and of course I like that kind of music too. Well my neighbor just came over to my house, knocked on the door, called me emo trash, and threatened to call the cops on me for "disturbance of peace"
WTH?! I like I'm doing something wrong now. Am I?

Unless your music is truly loud, just ignore them.
My stereo system is loud inside the house, but outside you can't really hear it.
