I don't like anything revolving around:
-drugs
-love
-money
-boobs
-butts
-how large boobs or butts are
-gangs
-guns
-hookers
-crime/violence
-how stupid the police are
so that basically eliminates 95% of mainstream rap. At one point I bothered to check out upcoming rap artists but after the 100th time of it being the same stuff I listed above I just stopped caring. I remember one time a person linked me to a really cool rap song that was actually had a nice meaning along with it. Wish I could find more like that :(
