There's the comment to which I'm replying. I've seen it 12 times in the theatre so far, and there just isn't time between songs to get bored with the movie. During most songs, they're developing a character. Whenever there isn't a song, the plot builds.
There's literally no downtime in the movie, except maybe where they bring in Katherine Baxter (Lucy Liu) before Roxie announces her pregnancy. (I found that part too amusing to be considered downtime.)
