LISTEN: Taylor Swift Sings About Another Breakup in New Song!

In her new single "I Knew You Were Trouble," Swift sings about being just "a new notch in your belt." So, who's it about?

Inquiring minds would love to know: Which one of Taylor Swift's ex-boyfriends did she know was trouble from the start?

The pop singer has debuted yet another song from her upcoming album, Red. The new track, titled "I Knew You Were Trouble," became available on iTunes at midnight Tuesday in anticipation of the album's upcoming Oct. 22 release, and it details yet another one of Swift's well-publicized breakups.

"'I Knew You Were Trouble' comes out tonight at midnight. Ready to hear more about my romantic misadventures????" Swift tweeted yesterday.

So who exactly is Swift singing about? Fans think it could be John Mayer or Jake Gyllenhaal, but really this track could apply to any of Swift's previous romances. The 22-year-old singer (who's currently dating Conor Kennedy) bounces between genres on the song, from country to dance to pop, and talks about a relationship that she knew would cause her problems before she got into it.

"I knew you were trouble when you walked in/ Shame on me now/ Flew me to places I'd never been/ 'Til you put me down/ I knew you were trouble when you walked in/ Shame on me now/ Flew me to places I'd never been/ Now I'm lying on the cold hard ground/ Oh, trouble, trouble, trouble," Swift sings in the chorus.

The song becomes even more honest when she sings later, "A new notch in your belt is all I'll be/ And now I see/ He was long gone/ When he met me/ And I realize/ The joke is on me."

Swift talked about the new single when she visited Good Morning America earlier this week, and she said that the song has a special place in her heart.

"It's a song that's one of my favorite songs on the album because it sounds just as chaotic as the feeling was when I wrote it. It's a song about kind of being frustrated with yourself because you have your heart broken and you knew when you first saw that person you saw all these red flags and you just went for it anyway," she explained. "So, shame on me."

If the song is about Mayer, you can be he'll have some not-so-nice comments to share. The notorious player wasn't exactly thrilled when he first heard Swift's track "Dear John," which was rumored to be about him.
