Shouldn't we add it in the Comercially Featured??? He did the Gamers OP with someone (iirc) and he did Osomatsu-san Season 2 OP too
I'm not sure though since he only did the song and not the vocals
Since this is utaite wiki, we focus on vocal activities (excluding voice acting) so if he didn't sing, then it shouldn't belong in the commercially featured section. It may be mentioned in his trivia if you want to.
What do you think?
