Thanks BRX, I hadn't imagined that pages that were not within the PDF could still be referred to like that. Worked very well. I decided to just scan the front cover of each album and use that as the PDF.

I wanted to also show the page numbers within the actual album where a song could be found but, oddly, PAGES isn't something you can place with the title formatting string. So I just duplicated the page numbers in the CSV as CUSTOM and used that to conditionally format the title.

So I'm pretty much home and dry, but I've not tested the workflow of inserting an actual PDF of a song yet.

Thanks for you help!
