I've been thinking that what I would like as far as "physical copy" of my media would be more like a card than anything that is actually used to play the media.

Something like an NFC-equipped greeting card (maybe more than just a cover; pages can be inside for fun stuff that used to be in the CD inserts/jackets/etc), that I could set on a stand which would then interface with the card and start playing music. Pull the card, playback stops. You get the idea. I just think something like that would serve both purposes - look and display nicely, while giving a conversation piece and more content from the creators; but not prone to damage causing issues with playback and as durable as you want them to be (could be more like HID Prox cards; plastic instead of cardboard. Or even more "exotic" materials. Lots of room for creativity).
