Back when I was in high school my roommate and I always had music playing all night. We'd pop a CD in and have it on shuffle play all night long. Once I got used to it I loved it. It would be just loud enough that if you woke up some the music would drift into your dreams. It was pretty neat.
I got out of the habit of doing that until I got my Audiotron. Now I usually sleep with music playing. As I was waking up this morning I had a lot of songs just entwining with my half-awake state. And it helped me get up on time (I still haven't reset the clock by my bed yet).
