^  I think you are mostly right. I heard a Diva needs both "light" and"dark" to keep the dragon tamed. Rin only has dark (Len only has light) so she uses her life energy as a substitute for light. In the end, it seems Len sings with Rin, providing the light and then they sacrifice themselves to put the dragon to sleep (forever?).
