I think it's this one: https://www.google.com/url?sa=t&source=w...0PHfjhNGRj

While it has bookmarks, they are for sections of the hymnal not individual songs.

I found it, thanks.

As you said, it has bookmarks rather than a way to go to individual songs.  I suppose you can break up a PDF somehow - do you do that in MS or in other software?

If it's not granular enough, then check out this forum to make your own CSV file.

No need to break up the pdf, just create the correct bookmarks. 

Alternatively, I've also used this program to make my own PDF bookmarks, which works really well. But the CSV approach is probably going to be easier.
