A lot of the music in the charts is horrible. However, there's also loads of bands making great music right now. For every 10 crap songs I hear, there's also that one band that suddenly pops up with a great song. Twenty One Pilots recently.
99% of everything is crap. But with hindsight we forget Rick Astley and... well, maybe not. But we overcame Wham. And Vanilla Ice. And the lambada.
