Look What You Made Me Do

Taylor Swift takes a heel turn on "Look What You Made Me Do," the lead single from Reputation. In the dark, dance-pop song, Swift sings about taking karma and revenge on several unnamed adversaries. Possible names that she could be addressing include Kanye West, Kim Kardashian West, and Katy Perry.

The clapback song was co-written and co-produced by Bleachers' Jack Antonoff, who previously worked with Swift on three tracks from her 1989 album ("Out Of The Woods" "I Wish You Would" and "You R In Love."

The song's hook follows the rhythmic pattern of Right Said Fred's early 1990s hit "I'm Too Sexy." So much so that Swift saw the need to credit the songwriters of that track, Fred Fairbrass, Richard Fairbrass and Rob Manzoli. Right Said Fred frontman Richard Fairbrass explained to NME how Swift interpolated their tune: "The title of 'Look What You Made Me Do' is based upon the verse of '…Sexy.' That's basically it. What's weird about 'Sexy' is that when people sing it, they sing the verse, not the chorus – nobody sings that. Everybody sings: 'I'm too sexy' – it's the verse that people have latched onto, not the chorus." In Taylor's song they adapt that rhythm and attitude of the 'Sexy' verse as a chorus – so they've just interpolated it differently, that's all it is. I'd be an idiot to complain about it. We've been really lucky to have been picked by somebody like Taylor, who is obviously very cool and very successful and open-minded and relaxed about it. She's not like some people."
