Well, she can't seem to sing on key half of the time. If that wasn't bad enough, her voice doesn't have power anyway so, if she did sing on key all of the time, she still wouldn't be anything special. As for her songwriting, a lot of her stuff that be gets played on the radio and what not sounds like one big music cliché. Most of her songs sound the same. She's also not the least bit country and she never has been. Just because somebody uses pedal steel, banjo, fiddle or mandolin, it doesn't make then country. Look at all the non-country artists who've used pedal steel--Robert Randolph, Cinderella, Bill Haley & His Comets, etc.
Taylor Swift doesn't deserve to be in the same room as the Taylor acoustics she uses--those guitars were built for guitarists that play more than just the same damn chord progression over and over and over and over.
