Unless it's an unusually complicated song, there can be several beats that can be played to a song. What you're looking for is the Goldilocks beat, if you catch my drift. What beat "feels" right for the particular song? So, I guess it all depends on your experience and creativity enough to try several different things. A good example is the Cissy Strut. There is no one way to play that song, just like there is no one way to make Borscht. It's like asking, "what wine will go good with this dish"? Is your first guess going to be right every time?
