I'm new to looking for relaxation/mood music, so take my input with a grain of salt, but after a couple hours browsing through Amazon.com the other day, I downloaded Llewelyn's "Reiki" album and have really been enjoying it. It's not so melodic as to attract my full attention, and does make me feel calm and peaceful. Only problem is that d/l'ing through Amazon, I think one of their tracks is broken - it cuts off just after 3 minutes instead of going about 5 minutes like the rest of the tracks. So if you look into that one, find a better place to download it than I did.
I also grabbed an album by Midori called Bonsai Garden. It has two half-hour tracks. I like that one reasonably well, also.
ELKmama, what do you have by Coldplay? I recently discovered them and love what I have, but I don't have a lot of exposure yet
Off to look up Krishna Das.
