Taylor Swift is talented and I generally like her music. But if her new song is crap, don't play it and stand by your decision. As a program director, you have the responsibility to program to your audience, not to whatever dreck Nashville or an artist puts out. From what you've said, your audience agress. If they want to hear it, it's available on itunes.
Too many times big music pushes talentless pretty boys/girls down our throats and that limits the amount of airtime available for those with talent. I applaud your action.
Now, play us some Ronnie Dunn or AJ.
