I think I know where I'm going with The Devil thing but it would help if you could post the lyrics. I can't make them out well enough to know if what I am thinking would even work.
Also, if you had to classify the work, or at least this song, or put in some sort of genre, what would it be? Who is your target audience?
In fact posting the lyrics for all the songs might be helpful. It's difficult for me at least to separate the tune from the lyrics, and if I struggle to hear the lyrics, it is frustrating and I will dismiss outright. I know you are aware of this, and can work it out with whatever kinds of machines and techniques you musician types use, but if you could post the lyrics along with the video, it would be helpful to some of us in our critiquing...I know that Cami mentioned something to this effect also.
If you are looking more for just critique of the tune, or are worried about Copyrights or something, I understand not wanting to do that.
