It took me a few listen-throughs for me to catch it, but I agree with whoever said it before, Nailed is (actually quite obviously when you really listen to the lyrics) from the point of view of Martin Luther.
No, it doesn't deserve it's own thread. But you don't know how many threads I had to restrain myself from starting since listening to the album! I pretty much want to start one after every time I listen to any of the songs! XD
