About CN master songs
Just to let you know, CN's post-event announcements always tell the next two master songs (and before masters were in the game, they did the same for experts). Thus you don't really have to wait for the songs to appear in-game before allowing them to be on the wiki. If you are unsure about anything on CN, you can ask me (go to my talk page or discord user670#9501 ) - I'm a Chinese. User670 (talk) 11:19, 10 April 2018 (PDT)
CN master songs, continued...
... but the announcement says it's rin rin rin instead.
CN Master songs, again...
... wait for the announcements. No one can ever know what the devs have in mind before they announce. A reasonable guess is June when they celebrate the server's anniversary.
