How about a descriptor field?

[Jeannot]

A field that serves to describe or identify a release such as: The 30th Anniversary Edition; The Original Motion Picture Soundtrack; The Deluxe Edition; The Remastered Edition; Volume 1; Box Set; etc. - I always disliked the idea of adding all these information into the title field.

Thank you for the feedback. We have always thought about the addition of edition field.
