QotD: On Genres

Do you tend to like music in particular genres, or are your tastes all over the place?  What are your most and least favorite musical genres?

Aha, it's a little difficult question for me. Everytime I asked this sort of question, I hardly answered it. mmm.... I like some "mathematical" musics, for example The Pachelbel's canon and Hot Butter's "Popcorn". And... ah I also like Ventures' "Pipeline" and Piazzolla's Libertango. Do you remember Libertango played by Yo-Yo Ma? I like the music very much and my friend Uda can play it with his self-invented instruments. It is astonishing! You can see the picture of his instruments here:

I can't describe it in English but its sounds are very excellent!
