I get what you guys mean. And I tried to make as much sense as possible.
I think I really learned the
harmony for "Heartplace" thinking it was the
melody.
Sometimes I wonder if what Ayu sings live is really the harmony, but I guess it's the melody. It's just that the lower part in the chorus (in the studio version) sounds more clear than what Ayu sings live. Either I just have a really good (or weird) ear (lol), or the balance between the harmony and melody is just so perfect. Maybe the harmony (the lower part, I'm assuming) is turned up more than what Ayu sings live so that it doesn't sound as awkward? I don't know, I just know that what Ayu sings live... I've never heard it before in the studio version. When she sang it that high I was like, "Wha...?"
