Not being the most puter -savvy person I would try a search to locate the person who did the music score for POTC and hope it would spin off from there.
Here is a link to one of my favorite sites. Top 100 Classical Music Scores. It is a sampler of all different types of music. Just look through the keywords and click on the “preview” next to it.
@justin5824 What exactly are you looking for? Just music that is similar or similar music that you can use legally in a film or video project of your own?
