Sorry, I actually would have liked you to leave the full path information now that you have the FastSpring version (unless you happened to copy every one of your mp3s into the Backing_Tracks folder under the LocalState folder listed in that screenshot). Relative paths are going to be relative to the location of the PDF. MobileSheets will take the path of the folder containing the PDF, then append the rest of the path to that and try to access the file directly. So based on our setup, an absolute path is probably best.
You can also try switching Settings->Display Settings->Render Preference, as that changes which PDF library is used which has an impact on how the links are processed. One may work better for you than the other. I definitely don't know why you are seeing the page number though, as I didn't see that with the files you provided to me. I do see that the path seems to be different than what I'm expecting. When I click on the pirates title, the hyperlink in the PDF specifies ../../Backing_Tracks/Pirates.mp3 which is causing issues. I'll change the logic to try looking for the file in the root of the storage location as a last resort.
