I think Taylor's first big hit was Tim Mcgraw, on her self title album Taylor Swift, which came out in October 2006. u should check somewhere else. im not 100% sure.
Her first song is Tim mcgraw she wrote it when she was 12 years old only Taylor swift promises to her family when she was young she was going to be a singer.
