Seriously

Some sample lyrics from recent pop music:

Sample 1:

Don't be fancy
Just get dancey
Why so serious? 

Sample 2:

I’m so sick of being so serious
It’s making my brain delirious!

 Sample 3:

Why is everybody so serious
Acting so damn mysterious

It's clear that there is concerted campaign to undermine the notion of seriousness being waged by the purveyors of bubblegum pop music. I think the most probably explanation for this is that there is a cabal of sinister people trying to persuade the yoof of today not to to pay attention to serious and important matters so they don't notice the bad stuff going on in the world today.
