Taylor Swift

American singer-songwriter whose career across six albums re-recorded and eleven studio albums has made her the best-selling music artist of the 21st century by several measures. Swift began as a country teenager and systematically expanded into pop, indie folk, and alternative without losing her core audience -- a transition that is nearly unprecedented in the industry. The Eras Tour became the highest-grossing concert tour in history. Beyond music, her influence on streaming economics, artist ownership discourse, and parasocial fan culture has made her a case study in how celebrity operates in the social media era.
