Before considering whether it’s worth cycling through psychobilly, I don’t even see much need to analyse whether those last pieces are in the right vein.
What I do want to mention is the reason why I think the Windfarm Commissioner works: it’s in first person. There may not the hubris or identification of ‘I’m a tiger’ ‘I’m the goo goo mup’ or ‘I’m a rockabilly rebel [from head to toe]’
I doubt you could go to town on this and have ‘I’m a Sellout Liar with a Flag stuck up my Arse’. There has to be a sense in which the singer is proud of their prowess.
While there’s an underlying futility to the position and the concept behind it, it travels along. Just because the subject is unpalatable doesn’t mean that the song can’t be entertaining.
Putting this in context of other energy sources both moves it away from being a rant (which doesn’t belong to this music form unless there’s now an ‘arguabilly’) and introduces humour, which is an underlying feature of the genre; tongue in cheek though it may be at times.
