Bad Blood

Single (Remix feat. Kendrick Lamar) | 1989 (2014)

“Bad Blood” is a song on Taylor’s fifth studio album, “1989” (2014). She wrote it about a betrayal by a friend. The remixed version of the song, featuring American rapper Kendrick Lamar, was released on May 17, 2015, as the fourth single from the album and reached  No. 1 on the Billboard Hot 100 chart.

The album version was written by Taylor, Max Martin & Shellback, with Lamar writing his verses on the remixed version. The lyrics of “Bad Blood” describe a betrayal by a friend. As Taylor said in her Rolling Stone interview in 2014:

“For years, I was never sure if we were friends or not. She would come up to me at awards shows and say something and walk away, and I would think, ‘Are we friends, or did she just give me the harshest insult of my life?’ Then last year, the other star crossed a line. She did something so horrible. 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 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.” — Taylor Swift

Much speculation has been made about who this song is about, with one popular theory suggesting Katy Perry. Perry seemed to think so herself, resulting in even more tension between them over the following years. Taylor only commented on the song’s lyrics one more time:

“That was about losing a friend…But then people cryptically tweet about what you meant. I never said anything that would point a finger in the specific direction of one specific person, and I can sleep at night knowing that. I knew the song would be assigned to a person, and the easiest mark was someone who I didn’t want to be labeled with this song. It was not a song about heartbreak. It was about the loss of friendship.” — Taylor Swift

In May 2018, Katy sent Taylor a literal olive branch along with a note in which she apologized for her past mistakes. The two have now put their differences aside and are friendly.

Kendrick Lamar said that Taylor reached out to him regarding the collaboration. “I’ve always been a fan of hers, and she was a fan of my music and she reached out and we got it done.”

The accompanying music video for the “Bad Blood” remix was directed by Joseph Kahn and features an ensemble cast of Taylor and her girl friends. The video previously held the 24-Hour VEVO record with 20.1 million views. It won “Video of the Year” and “Best Collaboration” at the 2015 MTV Video Music Awards.

The song received a nomination for “Best Pop Duo/Group Performance” while its music video won “Best Music Video” at the 58th GRAMMY Awards.

“Bad Blood” reached No. 1 in Australia, Canada, Israel, New Zealand, Scotland, and the United States, becoming Taylor’s third song from “1989” to reach the top spot in the US and the fourth overall.
