Hover over a colored section of song for information on the relevant motif. Motifs are colored to distinguish them, by an algorithm that's not quite perfect at making them entirely distinguishable some of the time, but I hope it's reasonably legible anyway. Diagonally striped sections are a significantly altered (e.g. sped-up or slowed-down) version of their motif, also judged somewhat arbitrarily.
Based on when I did the same for Jesus Christ Superstar.
