This is what happens when older people with more experience and knowledge and you let them compose music for today, you get good results. Whereas, you let Justin Bieber and One Direction make up their music, train wreck and car crash. This is actually a different facet of today's music I don't like. Teen heartthrobs composing music. The issue is not that it's not music, the issue is that their music is junk and pop trash.
Even if Justin Bieber has someone writing for them. The music is geared towards a certain demographic. Imposing on us that rap and this type of junk electronica dance music is what we should listen to.
