This is bullshit.There are excellent musicians, writers and artists out there. And they aren't all from the "old school", the young generations are excelling like the others, you just have to look for the.good stuff. .
The difference is that now you have a lot more of everything, and with more comes poor quality too, but there is still a good share of great artists.
There is nothing remotely artistic about this song. Its sad that people 'like' such music. There are nursery rhymes with catchier tunes and more artistry. Back in the nineties, we had teenage pop but the bands had catchier tunes and for whatever its worth in pop music, better lyrics.
And yes, Beiber is somehow to blame for all this.
