I have been listening to a lot of music from
http://www.kendavismusic.com/ for awhile now. It helps me relax, concentrate, sleep, etc. *VERY* Pleasing.
Go order a CD from there if you're intereseted. I reccomend Daintree Dreamtime as it's my favorite
And no, I'm not spamming, I just think the music/nature sounds is very good.
