As usual, a little research shows that this story is noting but BS:
BMI director Jerry W. Bailey issued the following statement: “The story originated with TMZ, which took gross creative liberty with the facts. BMI filed a routine lawsuit against a bar for not licensing music over a span of several years. (We file dozens of such lawsuits every year) On the two nights we surveyed music in the bar, there were ten songs we selected to include in the copyright infringement suit (because they were among the titles our researcher happened to hear). One was a Taylor Swift song. Our 400,000 copyright owners sign all the necessary contracts for such lawsuits when they initially join BMI. Other than by the sheer chance that Taylor owned one of the songs heard on the night our researcher visited the establishment, she personally has no direct participation in this copyright infringement suit.”
