I'm not really sure how you would classify my tastes in music. I can find something in just about any genre that I like, although I tend to stick to (classic) rock, metal, jazz, and blues for the majority of what I listen to just for the sake of listening. That said, there really isn't a genre that I dislike, especially in the proper context; there is a trick to enjoying most genres of music, and its different for each one. You have to learn to listen to the important parts, instead of focusing on the parts that are incidental to the genre -- so, for example, in metal, the vocals are just another instrument in the multilayered sound, while in rap, the vocals are a percussion instrument, but also very much the lead instrument, and the main thing you're listening to.
This holds true even for mainstream pop; it tends to make very good club music. I dare you to go to a club that's playing some Lady Gaga or some Katy Perry and not dance. If that stuff doesn't get you dancing, then it's because you're one of those people who refuses to dance, not because of any fault of the music.
Incidentally, Lady Gaga is one of the best musicians to truly hit the mainstream in decades. She's actually a properly trained musician (she even went to a conservatory in New York), and her music is honestly decent. It's actually pretty common for the guitar club at my university to just randomly break into "Bad Romance" while jamming at a meeting, and we tend to arrange it differently every time, because the chord progression works no matter how you play it; I've heard everything from soulful piano arrangements to driving rock guitar arrangements, usually made up on the spot by a musician who knows how to play around with chord progressions.
I guess what I'm getting at with the above paragraph is that modern pop (as in the style of pop that has shown up in the last two or three years) is far and away better than what came immediately before it; in the 90's and early 2000's, pop wasn't about the music so much as the music videos, with the carefully choreographed dance routines that even worked their way into the live performances. Pop in the early 2010's is finally about the music again -- argue about whether it's dumbed down for the masses or not all you want, but at least it's about hearing the music and maybe dancing yourself, instead of watching the "singer" dance to their own song.
