I used Registrations only--no Music Finder. I would have one bank per song. That way you can always see a list of the songs, and they were automatically put in alphabetical order.
I used the first Registration of the Bank to call up the style, text, etc., and the voice I wanted to start with. The other seven Regs I only used to have instant access to seven more voices. I would actually have some go-to styles in them, but when the Reg. Freeze was on, only the voices would change--nothing else.
It worked great for me.
