I do too, it really gives it a bunch of atmosphere.
Actually a lot of the Temples have good music, IMO. This game probably has some of my favorite dungeons.
I managed to figure out everything and now I'm in the second (more cool) part of the game.
I feel the same way. I don't get why so many people are saying it looks so bad. Not to mention it's rendering the game world twice from two different viewing angles (so it's not just streaming the image like in Smash or Mario Kart) at two different resolutions AND at a constant 60fps. When you break it all down it's actually pretty impressive for the Wii U.
