What would the world me like if everyone listen to the exact same music, if there was no diversity in genre and all that jazz!?
It would be really boring, and it would give lots of REAL musicians something less to sing about.
And you know what, music-style-fashion, everything, changes by decade, good music will come back again, and be better than ever! And then, we will be saying "you idiots!! You where just listening to Lady Gaga, Niki Minaj, Eminem and Skrillex!!! What the heck do you think you know about good music?? Do ya even know who Robert Plant, Kurt Cobain or Lars Ulrich are!??? Well if not, shut up and beat it!!"
So I don't know, no one is happy
