From the Youtube post: "What if there was a spin-off of "Supernatural" called "Purgatory" based on the storyline from season 8? Would you watch? Mock opening sequence for a pretend show, based on a storyline I can't get enough of. ;)"
In curiosity I looked up the album on Wikipedia, and found this description of the album by Dennis DeYoung of Styx:
the album's theme was the struggle to overcome self-deluding superficiality in order to affirm one's genuine value. This theme was reflected in the lyrics of the album's title track:
So if you think your life is complete confusion
'cause your neighbor's got it made
just remember that it's a grand illusion
and deep inside we're all the same
