Whilst not music, I find listening to http://www.rainymood.com to be great for concentrating. It's a 30 minute sample of a rain storm.

It got me through my Master's dissertation, where I had it on loop for hours at a time.

Fiddler tells me you can currently grab the mp3 from here http://173.193.205.68/audio/RainyMood.mp3 (this was especially useful for the times I wanted to be disconnected from the internet to focus on work).

Oh wow, this is brilliant. I had heard of rainy mood before, but I'm so grateful you've found an mp3 of it. This is going to be on my mp3 player all the time now.

Most of the time it helps me sink into deep sleep :)

Yep, add an extra point of help for those suffering with tinnitus (like me) and the site is suddenly made of gold.
