*sigh* that's my friend...
I wonder if maybe music is like all the other subjects in the world... every genre of music is just as vast as subjects like law, and history (of course musical genre's all have histories as well), and medicine, etc. So when music lovers like ourselves try to suck in everything, it's overwhelming. Imagine how it was for the lovers of knowledge when genetics were disovered? Finally they felt like they were getting somewhere, and suddenly there was a whole new playground. Ditto with relativity, dimensional physics, etc.
