The youngest artist to ever win CMA's Entertainer of the Year, Swift brought down the average country fan's age by about 20 years with her simple songs of teen yearning...and then she crossed over to pop, selling millions more albums in the process.  Country music hadn't experienced this kind of earth shattering, move-the-needle sea change since Garth Brooks. Swift was named the AP's Entertainer of the Year-- a title even Kanye can't steal from her.
