How do I locate best setting for various songs?

I’m a new user. I bought this so my teenage girls could have background drums for various pop and country songs they want to play. We can find some approximate beats just from trial and error but what’s the best way to find the EXACT BEST SETTING?

all i can think of is using this:

Well that’s helpful but not many songs there my daughters want to play. They want Final Countdown and 21. Neither on list.

Yeah. I hear ya.

I have the same issue.

I guess it is just too new in its infantcy to have a more comprehensive list.
