It’s Morrissey!
Morrissey wrote these lyrics:
"I still don't belong to anyone / I am mine."
They come from his 1994 song 'I Am Hated for Loving,' which can be found on his fourth solo album, 'Vauxhall and I." But let's face it, there's a very thin line separating a song called 'I Am Hated for Loving' and 80 percent of Taylor Swift's discography.
