I really love most of the music (especially the music from "Up") that plays in the Pixar Promenade area. It really sets the mood for the playful take on Victorian seaside pier that that area is. The 2010 loop was very "Main Street" to me and never really felt like it fit a seaside pier. The 2001 loop was just cheesy with the Beach Boys constantly playing.
That being said, what I don't love is the Incredibles loop playing down the way. In what world does that belong on a seaside pier?
