The lyrics are indeed hair raising, but I don't think it's that terrible of a thing overall. The verses have something of a Kill Uncle vibe about them, and the whole thing's infectious enough, really, if you can get past the truck that's coming out of his mouth.
Anyway I'm looking forward to the album. I quite liked the last one, dreary as it was at times. Relegating Drag The River to the bonus tracks was criminal, though. It's the most affecting thing he's put out in years.
