I like Jazz music, but I prefer more contemporary smooth jazz over classical jazz. My favorite genre of music is Jazz-Asian Folk fusion (Look up Hiroshima).
As for classical music. I am generally not a fan of classical music (except for a few Wagner, Tchaikovsky and Bach masterpieces). However, I really like military marches. Give me a good masterpiece from the Soviet Red Army Choir, the Democratic People's Republic of (North) Korea's army band, Nazi marching music or even a few pieces from the US Military :-D
However, I do not like country, punk, reggae, ska, pop or gangsta rap music at all.
