Just saying that I can sell a CD. So if a CD costs 10€ in the shop and I know I could sell it for 5€ on ebay, it only costs me 5€ to listen to the songs (admittedly, plus the work for selling it). Not suggesting to rip the CD and then sell it, but if you tire of the music, you can sell it.
Right, but originally you were talking about how the information in an MP3 file restricts your ability to sell it.
You can probably imagine how silly it would feel to make sure you lose your MP3 after selling it, and what would you even ask for the MP3? Fiddy cent ?
