You own the disk, but you do not own the music on it. The disk comes with a license to play the music only in a certain manner. If you do something that is not allowed by the license, you are not covered by the license and therefore you are liable under copyright for using a work you do not own.

If we start saying that "own is such an overloaded term, lets not use it anymore" this is the first step to giving up any ownership rights you may have had.
