WHY DON'T PEOPLE LIKE THE THINGS THAT I LIKE

It's funny that you're posting this because a few days ago two of my roommates and I (we 3 DSR guys) ended up in an hour long discussion that revolved around Mumford & Sons and the rise of Indie Folk in general. There's not really a point in it, they appeal to the masses by producing an inoffensive version of Folk with elements that are just unique and accessible enough to the casual music listener. It's not necessarily marketed towards people that are truly into music, who might find it bland and unoriginal (as the three of us do). Eventually this will pass and another genre will be hip and in to the public and we'll be making these types of articles about those bands. I've come off as a pretentious douche to too many people by trying to tell them that they music they like kind of sucks. That's not going to stop people from liking this band, it's not going to stop them from selling records, the best I can do is nod and show them other lesser-known bands that they might enjoy more.
