A band that is not and cannot be "emo." "Emo" is a word created to further the delineation of all music into tiny, highly-specified categories. It is a false label, much as "grunge" was in the early 1990's. Moreover, it is a recent term, new within the past year or two, while Weezer's Blue Album was released in 1994, quite a long time before some recording industry advertising hack created the term "emo." Weezer, having predated "emo" by a number of years, cannot therefore be "emo."
Weezer plays rock music, much the same as most all other "emo," "punk," "metal," etc. bands.
