Honestly? The game's soundtrack.
Failing that.
New Age Instrumentals.
Instrumentals in general.
[censored] words...
I have the soundtrack, I have to give it a few more plays, but so far, I'm loving it. Although I find it a little difficult to focus on if, for example, I'm on a bus with screaming children...
It depends on what I'm playing, but 90% of the time, music just distracts me from the game.
Same with me now, which is why I'm hoping to find something good to listen to while I'm away from the game.

Makes skyrim [censored] epic
It has been forever since I listened to Corvus Corax. I will definitely have to test that out, thanks.
