I liked a couple of the harp songs, but overall I wasn't a big fan of them. Especially since they existed to be used once during a story segment and then never again. The Ballad of the Goddess is nice, though, and the last one -- the Song of the Hero -- that just gets an obligatory two thumbs up.
I'll share a story, though. Early on during my first playthrough, in Faron Woods, I broke a pot somewhere and a fairy came out. I had full health at the time, so I continued on my way, leaving it undisturbed. Usually in previous Zelda games, if you didn't use or capture a fairy within about 10 seconds of finding it, it would fly away, disappear, phase through a wall, or something like that, and be gone forever. So I was really caught off guard when I wandered back into that same area at least a half-hour later and the fairy was still there, flying around like it was waiting for me to come back. I had been all around Faron Woods in that time, though of course not leaving the region for the Deep Woods or anything. That was the first moment the scope of the game really hit me.
