I have the Super Mario RPG remake to thank for getting me obsessed with these tracks:
Let's Try
Let's Go Down the Wine River
Dodo's Coming (Almost failed that jump, but I made it)
Steam Gardens
Peanut Plains (Puts me in a good mood.)
Pop Star
Aqua Star
Mii Channel (Brings back memories.)
Wii Shop (It makes me miss the Wii Shop Channel even more.)
