Lover is the seventh studio album by American singer-songwriter Taylor Swift, released on August 23, 2019, through Republic Records. As the executive producer, Swift enlisted producers Jack Antonoff, Louis Bell, Frank Dukes, and Joel Little for the album. Lover is primarily a pop, synth-pop, electropop, and pop rock record with a retro style, encompassing diverse genres such as country, funk, dream pop, folk, rock and roll, R&B, bubblegum pop, pop punk, and indie pop. Defined by Swift as "a love letter to love itself", Lover celebrates the full spectrum of love, using light and bright tones that depart from the dark nature of its predecessor, Reputation (2017). The album's music videos and art direction marked a change in Swift's visual appearance, which embodied a summer aesthetic consisting mostly of pastel colors.
Lover contains collaborations with Brendon Urie and The Dixie Chicks. It was preceded by three singles, all of which entered the top-ten of the Billboard Hot 100: "Me!" and "You Need to Calm Down" peaked at number two, while the title track reached number 10. Breaking a string of records, all 18 tracks of Lover charted simultaneously on the Hot 100, including "The Man" which peaked at number 23 and later became the fourth single. Lover was praised by critics, who commended Swift's songwriting conveying emotional maturity and growth; however, a few critics found the album lengthy and sprawling.
Moving 867,000 units first-week in the United States, Lover debuted atop the Billboard 200, giving Swift her sixth consecutive number-one album in the country. It debuted at the top spot in many others, including Australia, Canada, Ireland, Mexico, Norway, the Netherlands, New Zealand, Portugal, Spain, Sweden, and the UK. Lover was the best selling album of 2019 in the US; it has been certified 2× Platinum by the Recording Industry Association of America for exceeding 2 million units in the country. Globally, Lover was the top-selling studio album of 2019, selling over 3.2 million pure copies worldwide, and set the Guinness World Record for the biggest-selling album of the year by a solo artist. Swift had been set to embark on the Lover Fest tour in 2020 to support the album until the COVID-19 pandemic cancelled or postponed many dates to the following year.
Lover scored several accolades, including a nomination for Best Pop Vocal Album at the 62nd Annual Grammy Awards; the singles "You Need to Calm Down" and "Lover" were nominated for Best Pop Solo Performance and Song of the Year, respectively. The album's visuals were nominated for 17 MTV Video Music Awards, winning four: Video of the Year, Video for Good, Best Visual Effects and Best Direction. Lover further won the Favorite Pop/Rock Album at the American Music Awards of 2019 and Album of the Year at the 45th People's Choice Awards. Lover appeared on several year-end best-music lists of 2019.
