As Neil McCormick says in the Telegraph this morning (Feb 26):
It's a swinging, urgent rocker with an edgy little lead guitar motif and the kind of swaggering one-note declamatory vocal Bowie has been pulling off since the days of Ziggy Stardust. The track's driving forward momentum is counterbalanced by the melodic sweetness of Bowie's own "ooh ooh" backing vocals, a sheen of swimming strings and a Motown-style bridge.
