I feel that Miley is mocking the paedosadist elite in this video. I couldn't figure it out the first time I watched and listened to it, and frankly it creeped me out, but now I've gone through all the subsequent Miley Pizza references as well as Macauley Culkin's Pizza work it's fairly obvious. I don't know what kind of multiple Miley is but she's a multiple and her artistic output is pretty much an ongoing record of that.
If we pay attention to her costume changes (nobody has ever done more) and the songs she sings there's a considerable amount of agenda and biography, with some touching moments of raw honesty like the song with her MK (victim) godmother Dolly Parton (just listen to the lyrics). Nashville is/was a centre for programming and I suspect that seeps out in Robert Altman's eponymous movie if we're paying attention to the plain weirdness and inconsistency of the characters in it.
Nevertheless, Miley's obsession with dripping-in-cheese Pizza, for a self proclaimed lactose intolerant, is self evident for its symbolism. Please note the top photo is doctored with Pizzas but its too good not to use. The original is over here.
I wish I could say for sure this Miley Cyrus cover song is the real unplugged deal, but I don't know enough about the music industry to say so for sure in terms of production skills versus innate talent.
