Analyzing AC/DC lyrics is a pointless endeavor. I don't know what Brian Johnson is screeching and I'm better off that way. I just nod my head and go along with it. Phil Rudd's drumming isn't quite the minimalist masterwork it's been in the past, but it's still nowhere near the ear-splitting cymbal fest of, say, Alex Van Halen.
They're not as rude, hard, or nasty as they've been in the past, but there's still something here that works. In the '70s with Scott, they were a sex-obsessed, juvenile, bratty prank punk band. In the '80s and '90s they were a bit too old for that shtick and made some albums that were classic rock without a lot of classics. Now in their 50s and 60s, they don't have to put on a show for anybody. They're a barebones, no-frills rock band with classicist tendencies. It fits them. It works.
