I've looked everywhere for this soundtrack,it's the only one in the series I don't have, I wish I knew where to get it.

Hope this helps you out.

I warn you now, don't get your hopes up if you haven't heard it yet. If you expect it to be as good as "going commando" or "up your aresenal," then prepare yourself for a very unpleasant surprise. This soundtrack was a huge disappointment in my opinion.

Yup, thanks, why do you say its not the best? I liked the music from the game.

I didn't like how the composer switched from the beautiful and powerful melodies of the earlier series, to a dark ambient soundtrack. The music doesn't feel like other Ratchet games where there was often a sense of urgency, despair, or just plain chaos. But I'm glad you like it.
