Hey, Big Thunder! I've actually heard of the Dave Matthews Band! And heard them! Usually I'm not familiar with most current artists.
Another one with eclectic taste in music, although the basic requirements for me include a well-developed, complex relationship between melody, harmony and rhythm. I tend not to be fond of anything that emphasizes one thing too much over the other--although moments of brilliance are appreciated! :D
Classical music: more instrumental than vocal, although I do appreciate oratorio and opera when in the right mood. :)
Contemporary music: *Ahem* Generally considered to be written in the 20th century or later. I enjoy music from just about every era and genre. Not fond of country/country & western, rap, or heavy metal, for the most part--with a few exceptions, of course. :D
Jazz: prefer instrumental to vocal. Listen to KYOT (pronounced coyote) periodically--a local jazz station.
Musicals: from Lerner & Lowe's "Oklahoma" (generally considered to be the first musical that advanced the story through music) through Rodgers & Hammerstein's many works to more current composers and productions, including Disney's made-for-television musical movies. :) Although I really dislike Disney's version of Rodgers & Hammerstein's "Cinderella." I so wanted to like it--the performers are terrific--but many of the songs are out of order and don't advance the story properly--and it borrowed songs from other productions! They stick out like very sore thumbs!
And very opinionated about what I like or don't like! :D
