I don't see what the problem is. Did you notice that there was a mandolin being played there. That means that Taylor Swift(or her handlers) hired a mandolin player-- that means he got PAYED to play the mandolin. What's the problem? I think all the pop acts should have a mandolin in their performances,in fact it should be a requirement. Maybe a law. Anyone that pays someone to play the mandolin is golden in my book! Besides she's kind of hot.
Ever seen Taylor's dazzling Taylor 12 string? Taylor on the headstock and Taylor in layed into the fretboard. Talk about product placement! Too bad her name isn't Dudenbostel!
