Manic-depression. They're (a) very creative, and (b) very suicidal, i.e. they want to kill themselves (drugs) and everyone around them (socialism).
These don't necessarily make for a good song though. A manic depressive suicidal society where everyone is miserable doesn't make me want to sing in the shower. The creativity on the other hand, that one I'll give you.
Anyone who can turn "who, as you crawled out of the alleys of obscurity, sentenced to rejection in the morass of anonymity," into a lyric is aces in my book.
