Interesting, but don't people just buy mp3 instead of used CD? It might be a good idea to sell a usb drive full of songs, or songs that the user want instead of an obsolete city.
Well, I can't do that for bitcoins legally without getting into the market of itunes and the like, and this is not something I'm eager to do... really! CDs, on the other hand, are physical licenses to the music, and as such easily sold as used items. And the price per album is more or less the same as mp3s from itunes, and with a little work could be brought down.
However, I am more willing to buy used CD player for its scavengable DC motors, laser reader, stepper motors and other valuable electronics. Especially if it is far cheaper than buying factory rolled out and unused DC motors and other parts.
Scavenge for used electronics? Is that still useful these days? I have some computer hw laying around, cd units included (they should all be working), maybe I should make a list and send to you
Or put everything on biddingpond...
