UHH..nice wat did u do im curiouS...???why'd he say that to you....OH AND MY ANSWER IS.....SHE ALWAYS EITHER WRITES HER SONGZ OR WRITES 'EM WITH SOMONE ELSE..SO YEA SHE WRITES HER SONGZ
ok what song? did you like forget to type it or copy and paste a youtube link or something? but anyway...if taylor swift has it on her cd or something (except for you know the ones that were never recorded like id lie and i <3 ? and your anything and stuff....) then she probably either wrote or co-wrote it.
Taylor Swift writes all of her own songs. If she didn't 100% write it herself, she had help, but she always plays some part in writing the songs, unlike most musical artists. :)
