I have a couple samples available on my webserver: http://sapiensantiquus.endofinternet.net/spacerts/

One is a sort of majestic theme, along the lines of Star Trek, or the BSG theme:

YouTube - Broadcast Yourself.

It's, of course, a very short sample, but I just wanted to give an idea of what I was thinking.

The other one is actually an older song that I started writing in Garage band. It's kind of a an ambient jazz/techno song. If people like it, I would probably need to purchase a copy of garage band (I sold that computer). But I wouldn't mind the expense .

For some reason excessive editing of this post has been causing me problems.... a couple other videos I had on here got erased. Anyway, I just also wanted to mention that I like the music from Halo and Starcraft and I could probably produce something similar.

Chronicles of Narnia, some really good music.

I like the piano and string combo in this one. Nice melody too. The french horns are awesome too.

Oh, this theme from national treasure has some pretty awesome rythm/percussion stuff

National Treasure Soundtrack- The Chase	LQ | LQ+ | HQ

Good movie, good soundtrack. I figured it was worth reviving an old post that is still relevant.
There are other good songs on the soundtrack, but this one i think is most appropriate for a game soundtrack.
