I think you may be looking for more science in it than actually exists.
i agree, imo the science part of it mostly comes in the production of the track, not the mix in the club. good phrasing, key, levels, an stuff. not to mention the overall groove.
you could break every track down to it's individual sample and it would come out looking like a symphony score. but even in symphonic and classical pieces tempo, key, time signiture, rythem, etc. changes throughout the piece- personally i enjoy it...kind of that whole 'journey' concept. like the music starts in one place and ends in a completely different place but its still the same theme. ie: (classical) stravinsky's "firebird suite", (rock music) janes addiction "three days", (electro) any rabbit in the moon show.
like kushing said though, no one in the club is going to be sitting there analysing your conducting skills. Unless you're trying to make some mix tape or demo then all your tracks would have to be hand selected. also, personally im more interested in groovin to the tunes when im doing whatever it is im doing there.
...A Phd would more likely tell you about where the music came from and the sources it evolved from...the technicalities are the easy part. I think this whole 'mixing in key' thing is a little overrated..unless you're planning to whip out your sax and start improving over the track- its something to do in the bedroom when you're bored.
else i guess it just depends if you're trying to write a symphony on vinyl or just trying to blow up a club.
for info on keys a good site is:

to get a quick bpm count on something look at your watch for 10 seconds while counting the beats on the tune then multiply it x6 (same way the doc checks your heart rate).
