I don't agree that there are implied contract limits on your use of a CD. I also don't agree that there are normally any express contract limits on your use of a CD.
The OP references a letter from a poster who got his terms mixed up. He equates copyright law with a license/contract. That's not true. There ARE copyright laws which attach to the creative work and that would limit the use, but it's not a license.
In the end, the OP's premise is flawed regarding the music on a CD having a license attached to it.
