Will we ever get a complete Yakuza soundtrack ?????

I don't know exactly what it is, but there seems to be some relationship between POPHOLIC and MIT Gathering, so the POPHOLIC composers are probably the people listed in the MIT section: KIKU (Tomoki Kikuya?), EIJI (Eiji Kawai), and O-K-B (Kaoru Okubo?). Seems to lead some credence to my theory about the POPHOLIC composers for Yakuza 5.
