Taylor Swift is such a ubiquitous force in the pop world these days, it’s almost easy to forget she began her career as a successful country singer, releasing albums such as “Fearless.” The album finds Swift in a typical self-reflective mood, exploring personal relationships while name-dropping various people in her life. The album spent 11 weeks at #1 on the Billboard charts, the longest run since 1999–2000.
