Query: best relaxation CD

I knew a stressful period was coming up for me so I bought several relaxation CDs to help me fall asleep. This one worked the very best for me. I have even fallen asleep listening to it several times. Very relaxing mental exercises, voice, and music. I highly recommend it.UPDATE: I've been using this CD for nearly five years. I fall asleep to it at least five nights out of seven. It's so useful, I bought a backup in case something happens to my first one. However, my daughter doesn't like it as she prefers to fall asleep to just music. (Picking the right relaxation recording is definitely a matter of personal taste.)
