Thanks for the advice.
If you want to tweak with music you can get
Audacity . It runs on Windows (Macs too IIRC). Pretty useful.
I've used some Electronica from the Matrix Trilogy Soundtracks. Goes great with just about everything. Viking Metal is pretty good as well. If you want good background music you can just hunt down Soundtracks from Movies. They usually have some good scores, mixes, etc.
