Do you think there is enough evidence to add "showerheadz" as an alias for Kou Hayashi?
1. He is credited for the showerheadz remixes on the Illmatic Envelope OST.
2. In this PV for the Shooting Love 200X OST, showerheadz appears around 2:20 with his eyes blacked out. Going by the picture we have of Hayashi, it sure looks like it's him.
