This would be perfect for me, I love ambient music while doing almost any task, only 2 qualms tho. One being the high pitched beep when pausing/playing, it hurts. Second there isnt a volume slider. I keep different applications at different audio levels in the Volume Mixer, with chrome at full, making it very loud. Other than that, I love the idea!
I used to use this site, it really is a curated list of ambient mixes. Definitely useful for some people.
Music for programming... assuming you like ambient music.
42 and 43 hold a special place in my heart (not that I have listened to all the others)
