Taylor Alison Swift (born December 13, 1989) is an American singer-songwriter. An influential figure in popular culture, she is known for her autobiographical songwriting and artistic reinventions. Swift is the highest-grossing live music artist, the wealthiest female musician, and one of the best-selling music artists of all time.

Swift signed with Big Machine Records in 2005 and debuted as a country singer with the albums Taylor Swift (2006) and Fearless (2008). The singles "Teardrops on My Guitar", "Love Story", and "You Belong with Me" found crossover success on country and pop radio formats. Speak Now (2010) expanded her country pop sound with rock influences, while Red (2012) explored electronic influences. Swift recalibrated her artistic identity from country to pop with the synth-pop album 1989 (2014), while ensuing media scrutiny inspired hip-hop–imbued Reputation (2017). Through the 2010s, she accumulated the US Billboard Hot 100 number-one singles "We Are Never Ever Getting Back Together", "Shake It Off", "Blank Space", "Bad Blood", and "Look What You Made Me Do".
