I am a melodiophile...which is a pretend word I made up just now. It means I am much more likely to enjoy a song with a strong, stylish melody than a "voiceless" song caught up in its own ambiance or tonal competition.
As for my preferred genres, I like more than I dislike. (Most genres I am simply ambivalent toward; it's hard to actively hate.) Especially I am a fan of:
Classical (European, Russian, Chinese)
Celtic ("Celtic" in the popular more than the historic sense of the word)
Oldies (the rock 'n roll variety, mind you)
Instrumental Film Soundtracks
Video Game Soundtracks
