Agreed. The fact that he doesn't even really have a scream, but more so just a rasp noise, and his lyrics which don't really ever make sense.. The dude really isn't even a vocalist.
I even recall him saying once that he laughed at a fan for getting his lyrics tattoo'd because the fans read the stuff and think its gold on paper when none of it is serious.
Jon's lyrics haven't always been that way. He's always been cryptic, but his lines were far from the the sillyness of the latest album. I love Mess but I think of his lyrics in DTBM2 as a cop-out and disappointment/
