Regarding meditation/relaxation and free stuff, here's some things I've found:
This site
12 of the Best Free Guided Meditation Sites (Updated) lists a dozen sources. Yoga Journal also has a meditation section here:
Guided Meditations: Free Audio Meditations
You can find tons more by simply googling "meditation free."
For sound/music, googling "binaural beats" or "isochronic tones" or simply "relaxation music" will give you more than you can ever hope to listen to in one lifetime! I'm particularly fond of the sound of singing bowls, and also of music by Steven Halpern (
http://www.stevenhalpern.com/)--I like "Chakra Suite" and I also use his "Deep Alpha" and "Deep Theta" and find them beautiful and helpful.
Hope there's something useful in here for you--I find it amazing how these things that I previously found too "woo woo" have turned out to be more real than many of the things I thought were "real"...
