...what would it be?
What music or song would you have playing as you walk down the street or do whatever it is that you do.

Personally i would have Metallica's 'For Whom the Bell Tolls'. Maybe not the whole song, just the intro as its basicly long enough to be classed as a song. Its slow, heavy and angry and would be the ultimate way to enter a room. People would hear the music a mile away and expect someone epic to come walking through the door and then realise its just me
