Happy birthday, Ross!
Someone already mentioned nervous_testpilot, the composer for Frozen Synapse and Frozen Endzone, but I'm gonna mention him again anyway, because he's just that awesome. I only own Frozen Synapse and I suck at it. I probably have more hours clocked into listening to the soundtrack than actually playing the game itself. Everything he puts out is awesome. Here's the link again:

The next soundtrack is from an anime. A few anime soundtracks have already been posted, so I figure what the hell, right? I really, really like the Psycho-Pass OST. Have a listen:

My personal favourite tracks are:
- PSYCHO PASS
- Hou to Chitsujo (Law and Order)
- Sibyl System
- Inochi no Omomi to Songen (The Importance of Life)
