licensed CDs

What I thought was that the database should have some fields for licensed and re-issued CDs like "original label", "original release date", "licensed by" etc., and a check-box "re-issue" or "licensed". I use custom fields for it but it look ok, when it says when it says: "label - Irond; original label - Nyclear Blast", and it looks pretty stupid when it says "label - earache; original label - earache". And if I do not fill "original label" field, I can't sort the CDs by their original labels. Can something be done about it?

And one more thing: when I said about web-links section, which could be optional, I didn't mean that it should be like you did in version 5
