The test prep company misquoted her "Fifteen" song in their materials for an SAT practice test. Even worse, they misquoted her while criticizing her allegedly bad grammar ...despite the fact that they screwed up her words in the first place.
A page in the practice test quotes her lyrics as, "Somebody tells you they love you, you got to believe 'em." Errrch. Wrong.
The actual line is, "Somebody tells you they love you, you're gonna believe them." The actual lyric is not grammatically incorrect, unless you're technical about "gonna."
A fan called Taylor's attention to Princeton Review's mess up, and Taylor had a brilliant response. On Tumblr she posted, "Not the right lyrics at all pssshhhh. You had one job, test people. One job."
LOL! Guess not everyone is Swift smart.
