Miley's take on Blondie is a study in homage and contrast. The original version of this song was a disco/rock fusion built around a drum machine beat, with Debbie Harry's breathy falsetto driving the lyrics home.
Miley's take does MUSICALLY pay homage to the disco influence, with the obvious drum machine opening. There is, however, no breathy falsetto, instead being replaced by her trademark huge throaty voice.... and it works here, almost bringing a bigger desperation to the song.
This performance had such a positive review that it was released as a single and added to the digital edition of her album, Plastic Hearts.
