Got to be a tie between New Orleans Square and Main Steet. I love Dixieland jazz, but the pieces being played on Main Street have such an unabashedly "Disney" sound to them that you can't help but enjoy them.
I love Main Street music, especially the "Oklahoma" medley.
A quick note on a small thing, but it's a wonderful example of how differenly the current TDA managers think vs. the Pressler/Harris regime. I always thought the tram/bus loading area between Harbor Blvd and the Esplanade was pretty boring. I remember thinking, "They should pipe in the music from the esplanade over in this area. It would lend some energy to the area and remind people right away that they've entered the resort."
Lo and behold, on my last trip in September I noticed they were indeed playing music in this area. Again, a small thing, but those little details make all the difference, don't they?
Is this just for the lands or can it be attractions; because my favorite background music of all is the Splash Mountain queue area. When waiting in line they play a lot of songs from Song of the South and I love listening to it. I've noticed that they've turned the volume up recently so I can actually hear it clearly rather than trying to hear it over hundreds of other voices in line.
Every land's music is wonderful, I don't think I could pick one as my favorite. But since no one else has mentioned it, I'm very fond of the Toon Town background music, even if I don't get back to Toon Town very often. I love all the old cartoon themes.
