With the financial climate being what it is at the moment who doesn't want some free music? If you're into videogames at all then you might find something here that tickles your fancy and you can have it as a free, and completely legal ;-), download.
Soundtracks include -
SpellForce: The Breath of Winter
Empire Earth II
Obscure 2: The Aftermath
Jumper: Griffin's Story
Peter Jackson's King Kong
I haven't heard of some of these but I know from experience the Bioshock score is really good and I would imagine King Kong and The Hobbit being worth a listen. Also Viva Pinata is made by Rare so should be good fun. Even if they're not very good it won't cost you anything.
