After her hit single, Style, which hit #6 on Billboard Hot 100 and #1 on Pop radio, Taylor Swift plans on debuting her new single, Bad Blood, at the Billboard Music Awards (May 17). For this new single, she made a remix featuring Kanye West, one of the biggest rappers right now. Sources say the remix will also have a new production, made by Ariel Rechtshaid (known for his productions for Beyoncé, Charli XCX, HAIM, Madonna, etc.)
Her team plans on releasing the song to iTunes after their performance, and they will also debut the video. A situation similar to the "Shake It Off" release. The video will be directed by Joseph Kahn, like the Blank Space one.
More details will come in the future.
