In my opinion, Miley Cyrus has five distinctive eras. There's the Hannah Montana era (2006), the Breakout era, the Can't Be Tamed era (2010), the Bangerz era (2013), and the "Malibu" era (2017). People will say there are more...but...let's be real. Those are the big ones.
You can argue all you want in the comments and say that there are more and that Dead Petz should count...but go off. Not to me!
