She can save the black hair for when She becomes an actress and plays Audrey Hepburn.
I was going back through ATRL archives to see when Taylor started becoming a thing sales-wise. Some early highlights:
7/17/2007: iTunes
33. Teardrops On My Guitar
11/12/2007: Teardrops on my gutiar by taylor swift is moving up on the mainstream top 40 charts cause she's like @ #41 or #42 so that would make her the 2nd country artist to hit that chart
12/3/2007: If memory serves me correctly, BB has an exception rule where if a non-holiday song on recurrents sees a sudden surge in popularity again, then it can be brought back to the Hot 100.
Oh did Teardrops fall out of the chart? Huh. Did not remember this.
