Being part of a larger pdf shouldn't be a problem because you can create a file that is just the pages that make up the song you need. If you're going between the pages a set number of times then you can repeat the pages in the file structure as you need them and just keep moving forward through the pages (e.g. have the page structure be 3,4,5,3,4,5,3,4,5 or whatever). If you aren't going back to the start etc a set number of times then you could set one area of the screen to go the next piece instead of the next page (assuming you're using the screen to turn pages). Would that do what you want?
