The music of The Legend of Zelda: Skyward Sword is delightful. The musical trick the game's creators pull in the game's main shopping area, the bazaar, is one of the first things I discovered in the game that made me smile.
Lisen to the clip here to hear how the music changes as Link walks through the room. I first heard this trick on the Nintendo 64 in Rare's Banjo Kazooie. I loved it then. I love it now.
