This morning, music person Calvin Harris unleashed a Twitter tirade on his ex-girlfriend, more-famous music person Taylor Swift. Why? News broke that it was Swift, not Harris, who actually wrote the lyrics for Harris's newest hit, "This Is What You Came For (ft. Rihanna)." Harris didn't mind giving Swift credit, saying she wanted to stay anonymous when they were together. He did not like, however, the feeling that her "team" was trying to make him look like a thief. It escalated from there.
