When it comes to female mainstream singers, yeah, I totally get that. The 90's had several exceptions though.
Country-pop singer Kellie Pickler is one of the worst I've heard. Usually pop music like that just annoys me, but her song, "Best Days of Your Life" is one of the few to actually piss me off.
Aside from that, I actually tend to like women's voices more (real singing though, just sayin'). A lot of my favorite singers are female.
