normally i'd agree - and i've said the same in the past, but these days "pop" has become a word in itself devoid of "popular" and ironically most of the successful pop is not especially popular

culture has changed and the meaning of that word has changed with it

and who doesn't think of spears, aguilera etc these days when they hear the word "pop" rather than monica lewsinsky, bon jovi (yes they are a rock band still) and.... yada yada yada
