That's not "today's" music. Infact I'm shocked you put it in that category, there are lots of bands these days making good music, it's just there are a majority making bad.
I agree though, I hate crunk and any form of competitive rap/hiphop.
But there are some good types of hiphop. Like Apathy, Gang Starr, Rakim, Demigodz, Styles Of Beyond, Hilltop Hoods.
