I liked it. No, I loved the music. Sadly, none of them are that memorable to me at the moment. I can easily depict each instrument, or the family it's in, within each track in the game. I am a musician--oh. I can play a few themes too but that's getting a little bit off topic there..
The Skyloft theme sticks though because I can hear the woodwind(s), I think flute or another woodwind, at the start as it's a famous type of notation used throughout history, and it's just a relief to me and..well it just sticks.
Another is the "romance" theme which, even though it's not used frequently in Skyward Sword and only at the beginning when you're first talking with Zelda and her father/flying with Zelda on your "date". It's a cute theme--and I can play the violin "solo" part.
Every other theme, I know them when I listen but I cannot remember them. Forgive me, even the Ballad of the Goddess and Fi's themes bring tears to my eyes, I cannot seem to remember them..well okay. A little bit of the Goddess's theme.
