I do hear music while sleeping sometimes. The only genre I like to hear while sleeping is simply classical or sympthony music. I do this when I didn't get tired trying to sleep.
I usually have to have some kind of music on when I sleep. Preferably hip hop or christian. Every once in a sometimes i sleep with heavy metal. Not much though.
Usually when I hop into bed I have something on my mind and like to think it over before I pass out, so I find music that best fits with my minRABet. It's super relaxing. XD I use headphones because I can hear it better, but those damn bugs grind into your ear like no other.
I suppose it would depend on the persons mental reaction to what they listen to in regarRAB to whether you can sleep or not, ive tried it a few times one of the most interesting being ARH by Aunts Analog played on Repeat...
