In the summer of 1964 a young British rock band called the High Numbers released their debut single "Zoot Suit," and watched it disappear without a trace. The supremely-forgettable song was written by their manager Pete Meaden; a few months later, when they headed back into the studio, they decided to rename themselves the Who and let guitarist Pete Townshend try his hand at songwriting. It was a wise decision. The first single released was "Can't Explain," which kicked off a stunning two-decade run of music that paved the way for punk, metal, power pop and progressive rock. In honor of the Who's ongoing 50th anniversary tour, we have ranked their best songs.
