Being a musician (I play six-string bass guitar), I have varied tastes in music. Anything from the band known as "Tool" (especially songs like "Vicarious" and "Sober"), the solo piece "Cliffs of Dover" from guitarist Eric Johnson, anything from guitarists Joe Satriani and Steve Vai, anything from progressive jazz great Jean-Luc Ponty (especially the "Cosmic Messenger" album/CD -- absolutely jammin' bass lines), etc.
Anything that moves and has a great rhythm. However, music that will stop me in my tracks, and cause me to want to pick up a cue ball and hurl it at the source, are rap and "achy breaky" or "whiny" styles of country.
But alas, preferences, preferences -- like sphincters, we all have 'em!
