Jumping in here just a bit late. Hmmm let's see...I recently started using iTunes a lot for listening to music, and often times I'll be listening to some music while working on my MacBook or even while doing other stuff such as dishes. I don't really have a favorite right now, but when working in other apps and listening to iTunes I prefer something rather quiet because then I can still hear my screen reader talking. Even when a jazz or rock song is turned down a bit, it can get a bit much at times for that reason. Fortunately though I can control the volume of iTunes separately from the volume of the screen-reading software on my MacBook. But some artists I like to hear while writing are Enya, the Chieftains, and jazz such as The Dave Brubeck Quartet. The set of external speakers I got a little while back have come in very handy too though.
