atlantis seafret lyrics meaning

I'll never take back the things I said. So high above, I feel it coming down. She said, in my heart and in my head. Tell me why this has to end. Oh, no, oh, no. I can't save us, my Atlantis, we fall. We built this town on shaky ground. I can't save us, my Atlantis, oh, no. We built it up to pull it down. taylor swift the great war lyrics
