When you attempted to unlock performance you checked a box, as a digital signature, that said you would never play any song that you do not own the copyright for.

You do not own the copyright to answers, you do not own the copyright to dragonson.

Due to the contract you signed, you are not allowed to play those.

If you are using a program to perform them instead of yourself, that's also a violation of the ToS.

Course, everybody breaks the ToS in about 5 ways every single day of play. So, this is me basically not caring either.
