I'm a fan of the Remember Me soundtrack. It's kinda futuristic orchestral. A couple of the tracks have vocals of a sort, but in general it's pretty nice. The game itself was ironically rather forgettable, but the soundtrack is fantastic.
One can purchase it as DLC on Steam, or it may be available elsewhere. Or if you simply refuse to buy it, I have a download for it here: http://www.mediafire.com/download/2qz9t2zqh84t7h9/Remember_Me_OST.zip
I'm also a fan of the Gone Home soundtrack. It's very slow and ambient, nice for chilling out. I'm sure it's available somewhere, but if you insist, here it is: http://www.mediafire.com/download/rebj4zylk3aw18p/Gone_Home_OST.zip
