It's quite remarkable how this being revealed to be a Taylor Swift composition has seen this storm up charts worldwide, not just from outside the top 100 to #1 in the US but from absolutely nowhere to top 40 in the UK and top 20 in Australia and New Zealand. Taylor's power is absolutely remarkable, none of the other pop girls would have this impact just from being revealed as the writer of a song.

Do you mean Taylor wrote lyrics? Is it for the first time?
