Swift's third studio album, Speak Now (2010), spawned the two-time Grammy Award-winning single "Mean". Her cross-genre fourth studio album, Red (2012), earned Swift her first Billboard Hot 100 number-one single, "We Are Never Ever Getting Back Together". Swift fully transitioned to pop music on her next studio album, 1989 (2014), which made her the first solo female artist to win the Grammy Award for Album of the Year twice. The album included three Billboard Hot 100 number-one singles, "Shake It Off", "Blank Space", and "Bad Blood". Preceded by her fifth U. S. number-one single "Look What You Made Me Do", Swift's sixth studio album, Reputation (2017), made her the first artist in history to have four albums each sell over one million copies in their opening week in the U. S. Its follow-up, Lover (2019), was the world’s best-selling studio album of 2019. Swift eschewed pop for indie folk and alternative rock on her eighth studio album, Folklore (2020); the album and its lead single, "Cardigan", made Swift the first artist to have an album and a single debut at number one on the Billboard 200 and Hot 100 simultaneously.
