Oh no, not this trope again. Jesus, why does everyone need to try to compare things in a one-is-better-than-the-other context? It's absurd, and all it does is reinforce what people already think - this video isn't changing the mind of anyone that considers The Beatles to be grandfather rock. Great music was made then, and great music is made now. I notice all he made reference to was the teen pop that is currently popular, not bothering to go very deep with music being made today, just to try to prove a narrow point. And a quick Google search shows that plenty of people are making the opposite argument:
Why Music Is Better Now Than Ever Before
Plus, there has
always been terrible pop music. I was born the year that REVOLVER came out but can you guess what the most popular song that year was? Ballad of the Green Berets by Sgt. Barry Sadler.
Top 100 Hits of 1966/Top 100 Songs of 1966
There's a lot of other crap on that list which is no better than the pop being made today too. So I just say get over it, like what you like, but stop trying to "prove" we had it so much better and everything that came after sucks. Now get off my lawn.
