There's music in the land, but it's restricted. The left side of the land only has music whenever the drums are being used (it's pretty cool to be walking through when it happens, actually), and there's constant music over by the restaurant, but I'd say a solid third of the land has no music at all. I personally don't mind it; to me, the absence of music on the whole makes its presence stand out more when it appears, but it's a definite, noticeable departure from the rest of the park.
On Flight of Passage, opinions are opinions, but I'll say that for me it's an attraction that captures my attention from start to finish in the best way. It's how I feel riding Big Thunder Mountain, Spider-Man, Revenge of the Mummy, and Tower of Terror (along with others). For those four and a half minutes, I don't care about anything else except that I'm having the time of my life, ride system, budget, and all the other real-world factors be damned. It's the kind of experience that reminds me why I love theme parks.
