I'll be the first one to tell you I wasn't super duper impressed with many of the tracks. Right now, I only remember about four, because many of the were just plain forgettable. And out of those four, I only like one. Some people above mentioned that Hyrule King whatever song. I hated that. I much prefer the ALttP Castle Theme. It sounds evil and menacing, that your on top of the source of where all the trouble is. Then WW made it some kind of slow goodbye song between the King and Link, which I didn't like at all. I remember the Outset Island theme, mainly because I had to listen to it so much at the beginning. It was good, but not something that made me stand in one place and listen to it for a while like the Song of Healing in the clock in MM, or the Temple of Time theme in OoT/TP. Of course, how could I forget the Sea theme? So annoying......so many times...... same thing over and over........ugh.
I will end this post of a positive note though. I loved the Dragon Roost theme, There's a reason why it's featured in Brawl. I actually stood on the island and listened to it because it was so memorable. They really needed more areas like Dragon Roost in that game, because it's the only peace of music in WW I can say I truly loved and enjoyed.
With Oceans Theme and Gohmas theme on 2. and 3. 
The Opening Title song is included in my favorites because of the happiness it radiates. Hyrule Castle gives off (similar as to what DL01 said) a sense of royalty and the Hero of Winds is awesome too by how it gives off a sense of triumph.
