These are not part of the recording title. They should not IMO be part of the recording comment as this is not a version information.
Should appear nowhere.
Should appear either in release annotation or in a trackset title or nowhere.
Tie-up info (appears in this commercial or that film)
Can be set in recording annotation. Maybe we even have a recording-IMDb relationship for films.
I don't personally keep those info at all. Recently I came across at least one editor who really wanted to keep something. I would say in the track name, then, if it is not a release that I own...
