You put hip hop and pop together, but put a separate category for rap? That's interesting.
I listen to all those genres and then some, so it's hard to choose a favorite. I probably listen to more alternative than anything else, but I love hip hop too (real hip hop, not the garbage you hear on the radio these days).
As odd as it may be, my favorite genres are Country, Pop, and Rap. Weird combination I know. I'm a country kinda girl. Grew up in a redneck family haha. Rap, I find to be one of the most poetic forms of expressing yourself, and Pop, well if it sounds good to my ears... then I like it.
