Bad Blood (Taylor Swift) – 2014

Because Taylor Swift is known for being quite literal with her lyrics, it was relatively easy to figure out what “Dear John” was about. Between 2009 and 2010, Swift was romantically involved with American singer-songwriter John Mayer, and many have speculated that this song is about him.

“Half Of My Heart,” a duet they recorded in 2009, marked the beginning of their romantic relationship. And despite Swift’s refusal to acknowledge him as the song’s subject, there are lines in the song that make it undeniable that it is about John Mayer. Many of her songs are about heartbreak and we wonder why she bothers to hide this information anyway.
