""'I will not lie me down, this rain a-ragin'""

As I read that line, Marty, I believe the grammar is essentially correct.

I lie down, but I lay down my burden.

I don't see that the addition of the "me" in this case alters that, since the composer is not saying that he has picked himself up, and is now laying himself down again.

Since "lay down is what you do to something you are carrying, I think the word "me" is added for scansion purposes only, and I would not find it difficult to live with.

Now, of course, twenty people will tell us why that is wrong.
