Is there any online retailer that sells "resellable" mp3s?

I can't imagine anyone doing this, except by mistake, but do any music retailers or even just artists who sell mp3s that you are legally allowed to resell to someone else?

You've stumbled upon a door where your mind is the key. There are none who will lend you guidance; these trials are yours to conquer alone. Entering here will take more than mere logic and strategy, but the criteria are just as hidden as what they reveal. Find yourself, and you will find the very thing hidden behind this page.
