I think it's best to develop an authentic taste for something instead of relying on whether it's either popular or unpopular. And yes, that applies to people who just dismiss popular things just to be "edgy". True edginess is more like throwing molotov cocktails at Taco Bell.
“Everybody has a secret world inside of them. All of the people of the world, I mean everybody. No matter how dull and boring they are on the outside, inside
them they've all got unimaginable, magnificent, wonderful, stupid, amazing worlds. Not just one world. Hundreds of them. Thousands maybe.” -Neil Gaiman
