Interesting concept. And related to an observation I made a long time ago... a good song is a good song is a good song! Case in point is the song "Misty". Several years ago someone made a very upbeat jazz organ version... sounded great. Then I heard a medium tempo C & W version! At first I thought is was downright sacrelig, but after listening more I really liked it (I'm sure others will disagree).

Another example is one of my favorite standards "Dream a Little Dream Of Me". 2 excellent versions, 1 by Mamma Cass and another by Chicago (Night & Day Big Band CD) are totally different. It was also done upbeat in a movie titled with the same name.

A good song is a good etc!
