Alas, a few of you guys hate the genius that is Yamaoka.
Anyways, on-topic now. Osamu Kubota, SLAKE, Yoshihiko Koezuka (sometimes). Well, I'm not completely against Osamu Kubota, which is one of the prodigies in Bemani, but some of his songs aren't just my cup of tea. Same goes to SLAKE (although I've enjoyed the songs that are made under his other moniker SPARKER).
