Works with original medleys should be marked with that medley

@camelcamel2224 Please tag collabs that use an original medley with the medley instead of the individual songs (see this discussion). If there is no medley, then mark it as an omnibus collaboration or draft medley collaboration instead. This also applies to any collab with an original medley.

For this work specifically, you should mark the participants with their roles as well.

I'm Sorry about that. I'll check and fix it.
