Bad Blood

Taylor Swift transformed a personal grievance into a global pop anthem with "Bad Blood," the fourth single from her genre-shifting album 1989. Originally penned alongside Swedish production duo Max Martin and Shellback, the track blends synth-heavy pop melodies with hip-hop rhythms to explore the sting of betrayal. While the studio version sparked mixed reactions for its repetitive lyrics, the song found new life when Swift invited rapper Kendrick Lamar to join the fray. His verses added a gritty edge that critics embraced, helping the remix climb charts and secure a Grammy nomination.

Released on May 17, 2015, the collaboration became a commercial juggernaut, topping the Billboard Hot 100 and earning multi-platinum status across the US, Canada, and Australia. The song's cultural footprint extended far beyond radio play thanks to a high-budget music video directed by Joseph Kahn. This action-packed visual featured an all-female ensemble cast including Gigi Hadid and Karlie Kloss, mimicking the scale of a blockbuster film. The video swept major awards, taking home Video of the Year at the MTV VMAs and Best Music Video at the Grammys. Swift has performed the track throughout her subsequent tours, from the 1989 World Tour to the Eras Tour, cementing its place in her live repertoire. Following a dispute over her master recordings, she re-recorded both the original and the Lamar remix for 1989 (Taylor's Version) in 2023. [edit]
