Ditto on "The Miller's Son."
And I had no idea what the meaning of "What I did for Love" meant. Makes that song ten times more interesting.
For misunderstood songs, I think I would go with "Caberet" like others on this form, as well as throwing in "being alive" Many people take "Being Alive" as Bobby accepting marriage as a good thing in life (sondheim himself thought the ending was a "cop-out") but really it is just Bobby realizing not that marriage is good, but just that it is slightly better than the alternative. In other words, he is choosing the lesser of two evils.
Keep your morals, I don't have time. Keep your lovers, I'm changing mine!
