The song is originally a folk song, also covered by 60s folk artist Joan Baez, but Cyrus' screaming chorus shows it's Plant's version she's clearly channeling.
The comments on her SoundCloud post range from "I am sufficiently confused by this being unterrible" to "ekk, this is not a good cover. sorry Miley".
The singer has done some genre-bending covers recently, having recorded the Beatles classics, Lucy in the Sky With Diamonds, with the Flaming Lips for their upcoming tribute album of Sgt Pepper's Lonely Hearts Club Band, titled: With a Little Help From My Friends.
She's also known to knock out an unusual cover or two during her live performances and graced a Belfast audience with her version of the Smiths There is A Light, earlier this year.
