SaveMeMoon | Morning Musume - All 10ki Group Lines / 10期全員で歌われるパート集 @SaveMeMoon | Uploaded 4 weeks ago | Updated 5 minutes ago
As there will be no 10ki in the group soon I got nostalgic and decided to dig through every song to see which lines were sung by every 10ki member in the group at any time.

These are lines sung only by all and 2 or more 10ki members who were in the group at the time when the song was released. To be clear, if Ayumi and Maa sung a line together when Haruna was still in the group that doesn't count as the line wasn't sung by all generation members who were in the group at that time. Also not counting any of Ayumi's lines after Maa left as those are just her solo lines now that she's the only one left T T
