Bad Blood

This betrayal anthem finds Swift chronicling the tension between herself and another female musician. The songstress claimed to Rolling Stone that the bad blood between the pair arose after her rival "tried to sabotage [her] entire arena tour." "She did something so horrible," Taylor said. "I was like, 'Oh, we're just straight-up enemies.'" "And it wasn't even about a guy! It had to do with business," she added. "She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me. And I'm surprisingly non-confrontational ' you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it."

Swift told Rolling Stone that she hopes the press don't turn the lyrics into a 'gossip-fest'. "Sometimes the lines in a song are lines you wish you could text-message somebody in real life," she explained. "I would just be constantly writing all these zingers ' like, 'Burn. That would really get her.' And I know people are going to obsess over who it's about, because they think they have all my relationships mapped out. But there's a reason there are not any overt call-outs in that song. My intent was not to create some gossip-fest. I wanted people to apply it to a situation where they felt betrayed in their own lives.'"

Despite Taylor's concerns about the song turning into a 'gossip-fest' it did gander a lot of interest in the identity of the female musician who betrayed her. Media speculation centered on Katy Perry: An Examiner.com interview described how three dancers on Taylor's tour left before it was completed to join Katy's. Several sites pointed out that Taylor dated John Mayer before his relationship with Katy, which may have added to the friction between the pair. Katy herself tweeted a Mean Girls-referencing message ("Watch out for the Regina George in sheep's clothing") not long after the Rolling Stone interview hit the net.
