If a song title contains short or game version markers, the markers must be standardized to (Short Ver.) and (Game Ver.) respectively.I think it's better to add.
If an official cut version of song is used in a video game as an opening/ending/insert song, use a (Game Ver.) marker at the end of the current title. If there is an existing op version/short version/game version marker in the title, replace it with (Game Ver.).Or something similar.
