I definitely listen to music, it really adds to the energy of the ride and pushes me to push myself. Usually upbeat things. Electronic funy trance stuff like Sound Tribe Sector 9 is good until I get tired of it. Some upbeat reggae like Steel Pulse served well. Some Bob Marley here and there. Some Phish. I need some new music. Can't blast it, need to hear the bike/trail. Blasting it = too much of a disconnect from the world = more chance of me being careless and falling. I feel naked when I don't bike with music.
