I listen to a very wide range of music, including (and in no particular order):
Dubstep
Trance
Techno
House
Rock
Rap
I also listen to various artist that I don't necessarily like the genre as a whole that the particular artist pertains too. For instance, I love the british musician Dido, yet any other artist that sings her type of music I do not care for whatsoever. Another example, I love In Flames, which is melodic Death-Metal, yet I hate all other musicians in the genre.
As far as stuff I hate, I hate Metal, Country, and most Hip-Hop. I enjoy most of Lil Waynes old stuff (Dedication 2, Da Drought 3, etc), but his new stuff+most other Hip-Hop artist I cannot stand.
