In all honesty, there are a lot worse mainstream artists than Taylor Swift. She is probably one of the only semi tolerable ones. Plus I do disagree with your argument, artists and bands have been doing the sort of songs Taylor has been doing for years so I really don't see the difference. Of course there are others who deserve awards over her but pretty much every musical act these days who get "awards" don't even deserve them.
I quite enjoy Taylor Swift's music thank you very much. Corrupting the younger generation? Why do people say shit like this? When you were a kid did the media have that much of a influence n you that it formed your morals and values? No! Then why the hell would you think kids today would be any different.
And I could be wrong, but Taylor stepped away from the country stuff a long, long time ago.
