Castiel's mixtape

Castiel's mixtape is a gift from Dean Winchester to Castiel.

Overview
At an unknown point in time, Dean recorded 13 of his top favorite Led Zeppelin songs onto a cassette tape and gave it to his friend, Castiel.

After Castiel returned from a meeting with Joshua in Heaven, Castiel visited Dean in his room and attempted to return the mixtape. Dean handed it back, telling Castiel to keep it since it was a gift. Castiel was momentarily stunned and took back the mixtape.

So far, Castiel has not been showing listening to it.
