You left out "None of the above" and/or "Other". Like, I'm sure, several others, my choices don't fall cleanly into any of those.
If I gotta choose only one, it'd be Beethoven. All Beethoven - all the time. And no, that ain't classical as that'd include such lightweights as Mozart 'n the bunch.
But if I could mix 'n match, I'd halfta have American Traditional as a category. I don't mean country. Yuck! I mean traditional hillbilly music, cajun music, etc. Stuff that's just always been. I guess it's kinda folk, but not to be confused with the gawdawful stuff from the '60s. Examples're The Carter Family, Jimmy Rodgers, etc. up to and including Hank Williams 'n Bob Wills (but usually dating from the '20-'30s, though contemparies like Iris Dement 'n Emmylou Harris 'n that ilk do a nice job of keepin' it alive. Don't fence me in!
