That's interesting. I, too, enjoy all forms of music, but old rock gets the most airtime around me, followed closely by fifties and sixties jazz. I can't pin down a favorite rocker, but Hendrix gets a lot of plays, followed by the Beatles and Led Zeppelin. I actually enjoy metal, but I have to be in the mood for it. My favorite jazz musician is Miles Davis, especially his "Bitches Brew" era. Monk and Coltrane are also in the top spots, along with Herbie Hancock. I managed to work it out so I could meet him this summer. He is every bit as strange as his music. Bach is hands down my favorite classical composer, Tchaikovsky and Beethoven, tie for second place. That's kind of predictable, I guess. I only draw the line at rap, but I don't consider it music, anyway. I need to explore more Celtic bands, since I'm only familiar with the ones who came to the USA and made commercial successes of themselves. I know there are many more.
I listen to music about twenty hours per day - it goes off, sometimes, when I take my naps. A nap sounds like a good idea, right now.
