I came across this 'article' on Hipster Runoff today and after reading it and the comments people left, I couldn't help but feel a little out of the loop on the hating of The Lumineers. I have a hard time seeing how anyone could 'hate' that record, seeing as how it is such an enjoyable record.
So unless you are one of those people who only listens to a very small amount of genres (i.e. I can see how people who live on a strict diet of death metal would hate it), I can only imagine the major reason for hating The Lumineers is the fact that a lot of people now love The Lumineers.
It is a strange phenomenon and it happens all the time.
PS - I know that everything that ends up on Hipster Runoff is meant to be tongue in cheek / satire, but it still is based on real things
