So I missed the mark with my example, a bit, but in your immediate response, Mostapha, you talk about corporate evil, and that's where the Rage reference came from in my head. And that becomes a good example - liking and listening to rage does not prevent someone's playlist on their ipod from being "underground".
Think of it like this, though - in big clubs, there are "Main" rooms that play mainroom house. There are small rooms that play dub step (ok that's moving to larger rooms, but a few years ago it was, and still is in some places), then in another room, or maybe at another time (3-6am?) there is deep house, and all the while, imagine the club has a basement - that's where they play "underground" music, so whatever the people want to hear down there, that's what gets played. The stuff that can't make it upstairs.
In a way, I always imagined that this is where the term originated. Can anyone confirm this one way or another?
