I have the () album. Its great for studying.
I can't quite desipher what they are saying.
So far the only lyrics I can make out are, "You sat along the fire" I'm pretty sure those are the only lyrics cause everything else just seems like a variation of that.
Aside from that I like to go on Pandora and listen to the Album Leaf station.
However my current studying music (kinda studying right now) is a combination of TV on the Radio and Blur.
