The new CD and Album download is coming October 22nd for Taylor Swift and another song has been leaked from the album.

It's called "I Knew You Were Trouble", a song Taylor wrote along with famed producer Max Martin. Taylor talks about the song... "being frustrated with yourself because here you are heartbroken and you knew when you first saw that person, you saw all these red flags and you just went for it anyway, so shame on me."

I wonder if it's about John Mayer? You can get a KFFM first listen right now
