This clarifies the distinction between copyright and ownership of the material object in which it is embodied:
"Copyright Law of the United States of Americaand Related Laws Contained in Title 17 of the United States Code
Circular 92
§ 202 . Ownership of copyright as distinct from ownership of material objectOwnership of a copyright, or of any of the exclusive rights under a copyright, is distinct from ownership of any material object in which the work is embodied. Transfer of ownership of any material object, including the copy or phonorecord in which the work is first fixed, does not of itself convey any rights in the copyrighted work embodied in the object; nor, in the absence of an agreement, does transfer of ownership of a copyright or of any exclusive rights under a copyright convey property rights in any material object."
And the US Supreme Court's 2013 decision on "first sale doctrine":

Particularly:
"Here in the States we have something called the “first sale doctrine.” It simply means that once a tangible copyrighted work (or something with copyright in it) is sold lawfully the first time, the original copyright owner no longer has rights over the physical item. After that, the buyer can do whatever he or she wants with it — sell it again, donate it, whatever. That’s why you can legally hold a yard sale or sell computers on eBay. The resale right applies only to the physical item sold, not copies."
That protects the reseller of the original CD and subsequent resale of the material item through commerce.
