Considering how I (perhaps unnecessarily?) made the A Star Is Born soundtrack an exploration of musical-theater esoterica, a ranking of the new musical numbers from Poppins 2: Back in the Habit seemed a natural fit. Mary Poppins Returns does not technically descend upon theaters until next Wednesday, but its soundtrack of songs, written by Marc Shaiman and Scott Wittman ( Hairspray, Smash, Catch Me If You Can, Smash, Charlie and the Chocolate Factory, SMASH BRING BACK SMASH), is already available to all.
