(The concept and prose come from Paul Friedlander's Rock and roll: A social history; the graphic is mine):
One interesting way to learn about an artist or group, and to judge the impact of a song or album, is to ask yourself, What part of the body is most affected by the music? We created the Anatomically Correct Rock and Roll Doll for just such an exercise.
Consider the three major British invasion groups: the Beatles, the Rolling Stones, and the Who. My students would say the Beatles and the Who appeal to both the head and the heart--even though they don's sound very much alike. The Stones appeal to the genitals and feet. What do you believe? Try it with other artists.
