How is this funny?
It's cringe-worthy and makes no sense. And what's the comment on our society exactly? I just can't, it's just plain unfunny silliness.

They doing an awful job if they trying to pass a message.
Oh and that scene with the hat is supposed to tell us that they aknowledge the fact that they're huge sellouts that not only make commercial songs (I was fine with that as long as they still use traditional instruments, which they don't anymore) but worst of all, they also follow trends (tropical sound).
They excuse that because they don't take themselves seriously? No one should excuse themselves from making terrible music. Trash is trash, whether it's served with humour or not.
