Hi,
Thought I'd post this link as it has some of the best relaxation MP3's i've tried, and they're free (excerpts from a cd I think). They're from the Northern Ireland NHS website. Most of the other's I've had I hate the voice or they just don't do it for me. These seem to work a treat. Number 5 is amazing, a different technique to a lot of others I've tried. It's the only relaxation tape that's ever left me feeling totally relaxed.

The individual mp3's are found here if you want to stick them on a cd or mp3 player rather than sitting near your pc (Right click > Save Target As...):
