Rad 

A term used to describe a punk who doesn't restrict him or herself to one genre or another, though most likely has a certain preference. Describes one who is completely devoted to music; holding it and its ideals above all else. It is a state of such complete awesomeness that when someone achieves it, it will no longer matter to them.

Rad is for the kids whom Music=Life. See Hardcore Bandana
