Albums with Limited (CD+DVD) and Regular editions

[Secret Squirrel]

Just a quick note on some of today's submissions.

There are quite a few vocal singles that sell with 2 editions -- a limited edition with an extra DVD that includes music videos, and a standard edition which is the same minus the DVD. I thought we were treating them as independent albums, rather than using the parent-child printing relationship because the DVD is an entity that is of interest, and contains music that we can track here. We've got a precedent of handling it this way, like with these albums on the AVCD catalog (look for the duplicates).

Anyway, if linking them makes sense, we should do it, but we'll have to go back and change the other albums. Right now, I'm leaning towards separate entries. We can probably do some other kind of linking once we have this disc-as-an-entity relationship defined and implemented.
