About Taylor Swift
Lauded by The New York Times as "one of the most important pop artists of the last decade," and by Rolling Stone as "one of the few genuine rock stars we've got these days," 24 year-old Taylor Swift is a seven-time GRAMMY winner, and is the youngest winner in HISTORY of the music industry's highest honor, the Grammy Award for Album of the Year. With the 2012 release of her album RED, she is the only female artist in music HISTORY (and just the fourth artist ever) to twice have an album hit the 1 million first-week sales figure. She holds the record for the biggest digital sales week ever for a song by a woman, and for the second-largest song sales week overall, as well as the worldwide iTunes record for highest ever first-week album sales. With RED, Taylor became the first artist since the Beatles (and the only female artist in history) to log six or more weeks at #1 with three consecutive studio albums.

Taylor has an album on Rolling Stone's prestigious The 50 Greatest Albums of All Time (by women) list, and Time magazine has named her one of the 100 most influential people in the world. She is Billboard's youngest-ever Woman of the Year, and her more than 100 industry award wins have included the American Music Awards' Artist of the Year, the Country Music Association and the Academy of Country Music's Entertainer of the Year and three European Music Awards.

Taylor, who writes all of her own songs, has career record sales in excess of 26 million albums and 75 million song downloads worldwide, and her two most recent albums are two of only 18 albums in the entire HISTORY of music to sell more than 1 million copies in a single week. She has had singles top both the country and pop radio charts around the globe, and has thus far scored 13 #1 singles across multiple radio formats. She is one of the top 5-selling digital music artists worldwide, and is the top-selling digital artist in country music history.
