I turn on the radio to fall asleep, I listen to a station that doesn't have much talking or commercials at night, usually the songs played are from daughtry, lifehouse, nickelback, maroon 5, kelly clarkson, avril, qwen, linkin park, creed, etc. Recently, Elliot Yamin's Wait for you seems to be playing pretty much everynight this week.
I would use a sound soother but mine plays some annoying jungle sounds with monkeys, white noise i think(how can anyone sleep to this, sounds like a radio station with no signal), pier with damn owl noise constently and some lake with sounds like someone walking on it and making dropping splash noises. If only i had some normal sounds that would soothe.
