Mixing twee whistles with audacious dance throbs, ‘Fall Down’ is a clunky merging of Mlley Cyrus’ two previous musical identities, ie. country pop sweetheart and edgy electro vixen. In fairness, Cyrus does her best to sound interested as Will.I.Am compares her to an elevator, a doctor, a DJ, a lollipop, some whipped cream, a can of soda and the unspecified condiment that he likes to dunk his tortilla chips in. Move it along, folks. Nothing to see here.
