My friend told me about the Ai no Uta thing as well, and I told him that I would write a song called Ai no Uta and make it "anti-love" themed just for him.
I think Kumi has kinda slowed down recently, which is a good thing. I still expect an album by the end of the year, but I don't know if I expect another single or not. It's highly possible, but we'll see.
