1. Sweeney Todd - (Angela Lansbury, Len Cariou) - This musical is a masterpiece. Period.
2. Sweeney Todd - (Michael Cerveris, Patti LuPone) - Stripping it down is often best.
3. Urinetown - Songs should approach narrative more obliquely.
4. Avenue Q - The most obvious things are hilarious.
5. Showboat - I'm glad musicals aren't operatic still. (or) I'm glad Showboat invented the musical.
6. Oklahoma - Local colloquialisms in song depict place.
7. You're a Good Man Charlie Brown - Lack of vibrato represents innocence/youth.
8. Rocky Horror Picture Show - Don't be so wussy about campiness.
9. West Side Story - Melodic movement and rhythm encode emotion.
10. Follies - Musical is perfect form for nostalgia.

16. Hair - The tape distortion is just shocking!

18. Into the Woods - Every melody has its own meaning.
19. The Fantasticks - Piano centered score's not my favorite.
