I realize discussing this song is like discussing “Like a Rolling Stone” by Bob Dylan. It’s a song that so epitomizes the artist, yet has become so commonplace that there’s nothing more that can be said about it that hasn’t already been said better.
All I will add is that no matter how many times it turns up on compilations, films, and classic “alternative” mixes, I still can’t turn this song off. It’s a song that completely epitomizes the Smiths, yet is so much better than most of their catalog.
