The most likely thing passing through my ears would be Zappa or Bach (the two greatest composers of all time), with Miles Davis, John McLaughlin, Herbie Hancock, Ravi Shankar or Thelonius Monk being in the second rank. Recently, I've also really been enjoying the more current Amy Mann records -- great music, a great voice and she's an excellent lyricist. But the only kind of music I really don't enjoy is mainstream country music -- I'm pretty sure it causes organic brain damage.
