The best music that I have ever found is The Healer's Way Volume I & II by Stella Benson (http://www.healersway.com). You can find her two cds on amazon.com (and many other places online) - she also sells books that explains the logic behind everything on each cd. I haven't ever found anything else that is even close to her music. It is very transforming. She has played at the bedsides of many sick and dying people and has been able to bring them comfort and healing. I can't recommend her stuff enough. I find her website a little cumbersome, but don't let that deter you, you can find her music on amazon.com and lots of other places.
Also have you noticed the new Sonic Access program by LSC? I think this link will take you there:
http://www.learningstrategies.com/SonicAccess/Home.aspThis program has a lot of excellent stuff in it - well worth checking out too. The cds have a section with just the music which has a lot of good healing frequencies in it.
Another more unusual source of healing sounds is the Sound of the Bell by Thich Nhat Hanh -
http://store.soundstrue.com/aw00347d.html I find the repeated sound of the meditation bell very calming and steadying. The meditation cd is very good quality, the packaging is a little strange, but the cd is fine, you'll probably want to keep it in jewel cd case instead of the packaging it comes in which is a bit cumbersome.
I write these suggestions with the greatest hope that people can find the healing resources that they need.
