Yeah.

It has everything: Family feuds, drunken abusive boyfriends, fighting priests, plot twists, sexually ambiguous children, alcoholic children, milk, violence and (roughly) twelve lines that comprise of “la la la la, la la la la, yeah”.
All telling an intriguing tale that, as pointed out in the very first line, may not have a point.
It also goes on to explain that this story can be heard in many different forms, but the only one who really knows how it ends is the mysterious milkman whom we are advised to seek.

A compelling story with an indefinite and therefore intriguing ending and a catchy song to keep it all together (and cause the entire story to be stuck in your head for days).

Pretty straightforward. But the title alone, 3 simple words, does more work than most songs’ entire lyric sheet. The Mercy Seat is both the throne of God in Heaven, the top of the Ark of the Covenant into which the blood of the sacrifice was poured, and the electric chair on which the convict sits. These connections raise, without ever stating, some pretty intense questions about society, human nature, religion, and God.

As the song progresses, the chorus is repeated over and over, but with slight variations that change and discredit the original statement. The convicts protest of his innocence becomes more strained, and the brutality of the execution becomes less abstract and more explicit.

But if you include “Devil Went Down to Georgia,” is “Tribute” by Tenacious D not a good buddy for it?
