You must have had one "doozy" of fight for your wife to chuck out your prize possessions, similar to the woman who threw out her hubby's Detective Comic No.27 (the comic Batman first appeared in). I guess that this comic, if it still exist, is now worth well over $1 million.
It's highly unlikely that anyone will upload these albums for you to download, the authorities would get you both, and properly make examples of you.
Your best bet would be to contact the record companies concerned (or even the artists) and ask if they have copies that you can buy.
Finally, remember that you are allowed to backup your CDs and DVDs in order to protect your music and films from unforeseen accidence.
