Well, Ayu was being very different by giving us so many PVs for her Memorial Address album, so I don't think those are fair examples. She didn't even have album only PVs until Rainbow, anyway. Up until then, we really only got single PVs. (I'm not counting Connected because it was animated.)

As for I am..., Ayu had already created PVs for M, evolution, Never Ever (short PV), Endless Sorrow, Dearest, and Daybreak. I don't think an extra PV was necessary for the promotion of the album. Frankly, if Ayu was going to create a promotional PV for I am..., she should have done one for the song I am... to go along with the album name and the CM.

Although, I agree with you. A Naturally PV would have rocked. Especially if it had been a full length version of the Visee CM!!!
