I suppose, not all songs, published before vocaloid release, are demo songs. For example, Mayu and IA "Innovation" duet. The purpose of demo song is to show a vocaloid voice abilities. But when it mixed with other voice, this purpose cannot be achieved. So it is not demo song.

Let's qualify only "Ama no Jaku", "Caramel Sugar", "One More Time" and "Dreamin" as demo songs. And for others we have Youtube list page.

If you don't agree, with all songs from "MAYU SPECIAL 2CD" table will stretch to more than 40 rows. So it's just beginning!
