Alwyn in September 2016. She wrote the song "Better Man" for country band Little Big Town; it earned Swift an award for Song of the Year at the 51st CMA Awards. Swift and English singer Zayn Malik released a single together, "I Don't Wanna Live Forever", for the soundtrack of the film Fifty Shades Darker (2017). The song reached number two in the U.S. and won Best Collaboration at the 2017 MTV Video Music Awards. In August 2017, Swift successfully sued David Mueller, a former radio jockey for KYGO-FM. Four years earlier, Swift had informed Mueller's bosses that he had sexually assaulted her by groping her at an event. After being fired, Mueller accused Swift of lying and sued her for damages from his loss of employment. Shortly after, Swift counter-sued for sexual assault for nominal damages of only one dollar. The jury rejected Mueller's claims and ruled in favor of Swift. After a one-year hiatus from public spotlight, Swift cleared her social media accounts and released "Look What You Made Me Do" as the lead single from her sixth album, Reputation. The single was Swift's first U.K. number-one single. It topped charts in Australia, Ireland, New Zealand, and the U.S. Reputation was released on November 10, 2017. It incorporated a heavy electropop sound, along with hip hop, R&B, and EDM influences. Reviewers praised Swift's mature artistry, but some denounced the themes of fame and gossip. The album debuted atop the Billboard 200 with first-week sales of 1.21 million copies. Swift became the first act to have four albums sell one million copies within one week in the U.S. The album topped the charts in the UK, Australia, and Canada, and had sold over 4.5 million copies worldwide as of 2018. It spawned three other international singles, including the U.S. top-five entry "...Ready for It?", and two U.S. top-20 singles—"End Game" (featuring Ed Sheeran and rapper Future) and "Delicate". Swift launched the short-lived The Swift Life mobile app for fans in late 2017. Reputation was nominated for Best Pop Vocal Album at the 61st Annual Grammy Awards in 2019. At the American Music Awards of 2018, Swift won four awards, including Artist of the Year and Favorite Pop/Rock Female Artist.
