‘College rock’ is a hilarious and cruel name for a genre, at once condescending to the people who don’t ‘get it,’ and effectively painting the people who do as Poindexters lugging textbooks around. In truth, none of these songs that got popular on college radio stations in the 80s require a degree to enjoy. R.E.M., the exemplars of the style, may feature Michael Stipe’s mumbled and esoteric lyrics, but their song structures are traditional, their melodies clarion-clear. (And sometimes, like on “So. Central Rain,” they write a chorus anyone who’s ever made a mistake can appreciate.)
