Yikes! I don't think I even like 10 styles? Ah well, let's see...

1. J-pop
2. J-rock
3. Baroque
4. Classical
5. Opera
6. Ambience
7. Techno
8. Hip hop
9. Rock
10. Punk

But, really, my list stopped at Ambient music. xD; I tend to really enjoy music without vocals, or just a cappella. ... Or in a language that I don't understand fluently. It helps me concentrate.
