Collaboration?

[kumikomishitate]

If Koda Kumi and Ayumi Hamasaki did a collaboration, I don't even think they could write "feat." given how big each of them are. It's have to be Koda Kumi AND Ayumi Hamasaki. XD But I doubt that will happen though. I really do wish Utada Hikaru and Ayumi could collaborate considering they seem to possess the skills that the other needs, and thus they could make an awesome song. uu;
