The only music I hate is that untalented crap where they get a simple beat, repeat it over and over again, and get some women to say some gibberish that sounds slightly sexual.
Repeat, repeat, repeat. More and more of this crap comes out every day, I wonder how anyone can tell them apart.
Generic rappers piss me off as well. Their music has zero originality.
Lately, i've noticed more acoustic-guitars, jazzy singers, and all that stuff on the radio, which is way more welcome than something that just sounds like it's been forced through a win98 computer.
