Alright, i don't like giving away my secrets and all but i know what it's like to search endlessly for a soundtrack you don't even know exists. The complete mummy returns score pops up on ebay every so often in some form or another. however, if you don't feel like waiting for it on ebay, check out arksquare.com it's a japanese specialty store (in english) they have the mummy and the mummy returns at a fairly resonable price.
