If you've spent any time on the internet this summer, you may have encountered a certain refrain accompanying particularly fierce dance videos—"I've been a nasty girl. Nasty, nasty, nasty." This track, "Nasty" by the R&B singer and songwriter Tinashe, is a jam in its own right. Far from just a piece of viral content, "Nasty" is one of the songs of the summer, a chance for an burgeoning artist to reach a new level of success, and the latest in a long line pop songs from Janet Jackson to Beyoncé and Destiny's Child, taking the term "nasty" and spinning its on its head. "Nasty" is also a song that, in some ways, is ridiculously simple.
