People close themselves off from liking stuff, don't they. I do it of course, you close your sympathies off, strangle them in the cradle, I'm not the sort of person who likes this, that would entail a personality shift, new clothes, new friends.
This is also a (for want of a better word?) political thing, in that some people would feel that because mojo didn't include more diverse music than this all the stuff in this top 100 is condemned by association as being shit. And then you've got the reverse mojo feeling of "they're just ticking diversity boxes here, this really isn't good music".
Nobody can be right or wrong, our motives and sensibilities are never "pure". Which only really matters when you're arguing about music on the internet.
