Meh, only Tiki Tiki Tiki Room is untouchable. Everything else it open for debate/consideration
Let's all sing like the birdies sing... in the Tiki Tiki Tiki Tiki Room.
Those two are iconic the rest can be subed for new songs. Let's all Sing might not have been written for the attraction but it's still synonymous with it, IMO. The rest of the songs are easily forgettable. Much like the Moana soundtrack, fwiw.
