You idiot. Johnny Cash is a country singer. If he's doing synth pop covers, what do you expect? A better comparison would Marilyn Manson's version, which I actually haven't heard. I will though, because that album comes with all his videos.
You won't understand or appreciate Johnny Cash without understanding or appreciating country music. Which is ok, and as it should be, what I disagree with was Cash's placement as Gen X Crooner 2.0 (prototype was Tony Bennet), because you can easily create a facetious appreciation of Cash, be you a mall brat like CM Funk, or an indy fag like Incandenza, but if you have no connection with country music at all, you're not going to get Johnny Cash.
I know people talk up Cash on here, but nobody gets him, except maybe Downhome, and myself, because my musical taste is the broadest and deepest of anyone here, and Downhome's a bumpkin.
