Redefining Classic Rock


Or, why you (and me) just realized you are one of the olds.

Led Zeppelin is classic rock. So are Mötley Crüe and Ozzy Osbourne. But what about U2 or Nirvana? As a child of the 1990s, I never doubted that any of these bands were classic rock, even though it may be shocking for many to hear. And then I heard Green Day’s “American Idiot” on a classic rock station a few weeks ago, and I was shocked.

It was my first time hearing a band I grew up with referred to as “classic rock.” Almost anyone who listens to music over a long enough period of time probably experiences this moment — my colleagues related some of their own, like hearing R.E.M. or Guns N’ Roses on a classic rock station — but it made me wonder, what precisely is classic rock? As it turns out, a massive amount of data collection and analysis, and some algorithms, go into figuring out the answer to that very question.

FiveThirtyEight breaks down the math of what exactly defines a musical act as “classic rock”.
