Sorry, Doctor. I must respectfully disagree with your diagnosis. Radiohead's admittedly uneven excellence is due to the fact that they take fairly substantial artistic risks. Where do we hear risk-taking in Nickelback's music? In fact (not to bash Nickelback's very people-pleasing formula), where do we hear any attempt at art in their work? It may well be that die-hard Radiohead fans overestimate the degree to which the band has affected the music world; but leaving that aside, it is undeniable that albums such as The Bends and OK Computer are very fine pieces of work that stand with anything wonderful ever recorded in popular music in the last 50 years. Good is good.
