I can't pick a favorite category. The music I listen to depends on my mood at the time. I like certain numbers from Broadway shows, and certain themes from movie soundtracks.
I like Chopin, Rachmaninov, Borodin, Tchaikovsky, Debussy, etc. etc. etc.
I like almost all of Verdi's and Puccini's operas, and try to listen to one of them every weekend.
I like most of the folk classics from the 60s and
I love anything sung by Joan Baez or Mickey Newbury (Anyone else like Newbury?)
And IZ (Israel Kamakawiwo) Hawaiian music makes me
And Mark Knopfler and Bing Crosby and Peter, Paul and Mary and Pink Floyd and -- OK, I know when to stop.
