Apparently, pop music’s junior bimbo queen, Miley Cyrus, recorded a cover of Led Zeppelin’s "Babe, I’m Gonna Leave You." The song appeared on Zep’s self-titled first album, and was itself a cover of a folk song by Anne Bredon. I guess Miley thinks this might confer on her some sort of musical gravitas. I’m not sure why she thinks she’s lacking in that department. Didn’t going out in public wearing pasties, swinging naked on a wrecking ball, and twerking on stage with a big foam finger already bestow boatloads of credibility on Billy Ray’s little girl? If not, she can always record a music video for this song. Wearing nothing but a few strategically placed Post-it notes. Yeah, that ought to do the trick.
