What makes music boring?

Steven Hyden attempts to answer the question, unsuccessfully:

Bon Iver, Fleet Foxes, The Decemberists, St. Vincent, Wilco, Coldplay, Feist, The National, Grizzly Bear—I like some of these artists, and I don’t like others. They’re all pretty different, but they all have one thing in common: They’re “boring.”

I don't know if they're boring or not – frankly, I couldn't care less; I like them. Except for Coldplay: I've talked about this before, of course.
