The only place I can shoot doesn't have any music playing, and I'm sure they don't allow boom boxes at all. The earpieces under the muffs might work, but I could see the RO's at my range telling people that they need to be able to hear the RO's commands, so that would ban all methods of listening to music. Since they walk back and forth usually, they'd notice the wire going to a CD/mp3 player (or see you pushing the buttons), and ask you to remove them while shooting.
IF I were to go somewhere when music could be played, I'd definitely throw in DISTURBED. They're the best! Their new album (ten thousand fists) rocks! Of course, their first two albums rock as well.
