The Visit is absolutely gorgeous. The music is exquisite, classy, and romantic. It took a while to get to Broadway but it matured like a fine wine along the way. It's impossible to choose a favorite song.
Cabaret will always be a favorite. While the original is great, the show really came together in the 1998 revival. They were able to combine the best parts of all of the previous productions and the film. My favorite song is What Would You Do?.
The Scottsboro Boys is incredibly disturbing but phenomenal at the same time. It's just a brilliant show that, like The Visit, deserves more recognition. My favorite song is Go Back Home.
