People don't go to a Biker Bar to hear Avant Garde jazz; likewise, it's unlikely that the clientele that patronize this place want to hear the Electric Slide or Cupid Shuffle. Or, if you do get one, just follow Paul' advice and politely say 'no' or 'sorry, I don't know that one'. And if that segment of the crowd doesn't come back, you're ahead of the game.
