i actually completely agree with you. the drums in parts are nice in parts, as you said the guitar is great, and i also noticed that the bass has been brought out more, which i like.
but honestly, i'm the other way. Jon mess is the only 'let down' for me. i mean, don't get me wrong, it's still great, but it's a bit too much in parts and like you said, completely incomprehensible. i agree with you that jonny is way too relaxed in this track, i want more from him, i want that raw sound he used to give, not this chilled out shit (still love him though.)
overall, the thing i'm really disappointed with is the lyrics. of course i'd need to see them written down because i can't understand 75% of them (lol) but from what i can tell, it's pretty average. the lyrics were what i loved the most (after jaycee) in DBM1 (see: surprise! i'm from cuba), they're just so funky, random, soulful and passionate. kind of a beautiful mess.
oh yeah, and even though i wasn't exactly Kurt's biggest fan, i do agree to some extent that his voice would be more fitting.
