“My Apple ID is different then my wife’s. How do we share?: My wife and I are trying to share our music that is on our desktop. We have separate accounts and Apple IDs. How do we share the music without using just one of our Apple IDs on our own devises?”

Accounts cannot be Merged:
Merging Apple IDs is is not an option, as of this reply.
