With the school year beginning, I'm gonna be doing maths/physics plus writing history and geography lesson in short, and I do all this stuff while listening to music. I prefer instrumental music in this case. And if I keep this up, Ghosts I-IV and The Social Network OST are going to be the only music I hear. Apart from that, I know two God Is An Astronaut albums, and... well that's pretty much it. So, I need recommendations for instrumental stuff. Be it bands or OSTs, gimme anything. Generic dubstep and EDM not accepted. Thanks in advance.
