Why do schools play music that are just crap?

children these days like the stupidest things. Disney was so amazing in the old days. Not old old days but like in the 90's. Today, theres only hannah montana, jonas brothers, and no cartoons anymore. Those "singers" shouldnt even be considered singers because their just a bunch of fuking amateurs. Their off tune all the time and their songs are CRAP! But dont worry, thet will go away one day. But in my world, they have never exixted.
