the kind of overratedness (is that a word?!) that annoys me the most is when someone says about a band/artist "you HAVE to like them, because they're so influential!"
i've heard that line (or variations on it) in relation to several bands, most often the beatles - yes i appreciate that they're been hugely influential and most of the bands/artists i enjoy wouldn't be here without them, but i still don't really enjoy more than a handful of songs from their entire discography.
