It's also weird to think that Madonna, whom even her biggest fans would say is not a particularly gifted singer, is one of the very few to introduce two Best Song Oscar winners.
"Back in Business" is used as background music in a montage, so it's not really memorable in the film. There's another Sondheim song, "Live Alone and Like It," that is used similarly. I think "Sooner or Later" is just okay. I think "What Can You Lose" and "More" are much better songs.
