Without wanting to sound like an old-fart(I'm 35), I cannot imagine that anytime in my youth that I would have been happy listening to that.
In terms of sales, I may not be completely up to speed with this, but aren't charts now mainly based on streams. So, for example if people hear about a terrible song they may go and listen(for free) just to find out how bad it really is - this wouldn't have been the case in the past as people would have to pay for a physical copy
Think about how a streaming chart works - if people think a song is shit they are only going to listen to it once, or they won't share it. To reach the top of the chart you still have to be the most popular song.
