During a panel at the 2017 Supernatural convention in Minneapolis, Jensen Ackles and Jared Padalecki, in response to a fan question about which songs were on the mix tape, answered that they thought the songs on the tape were probably the ones referenced on the show (as of the end of season 14, this only accounts for 12 songs and 1 album - see above).
