All possible Kaya songs
I found this website which is probably the production company that produced most/all the songs from Kaya (TV series).

go to this site, and scroll down to see the names of those songs, and click on any name and they will play High Quality 45second clips of the songs. I wonder if there would be any way to get these songs by contacting them, but we'll see. I don't know why, but it's been a year or more since I heard these songs and I had to find out if they still exist.
