If a rhythm game does a collab event with another rhythm game in which songs from one game appear in the other, are songs from the game where the songs are originally from still permitted?

It really depends on the source material, I think. If a PJSEKAI original song was featured in BanG Dream, neither of them would be acceptable. If a Dynamix song was featured in BanG dream, Dynamix would be listed as the source material of the song. If a Dynamix song was featured in Arcaea, it would have to be a special Arcaea-version mix to have Arcaea be listed as the source material.

I think you can generally ask, 'is this rhythm game a rhythm game, or an idol/card collecting/gacha rhythm game?' to determine whether or not I'll accept it, which is limited to the former.
