On Ke$ha’s second full-length, the pop star-lightning rod has again enlisted the aid of multiple producers and songwriters per track in a Hollywood script-doctor approach to music that’s either the death knell of “authenticity” or business as usual, depending on your cultural exasperation level.

In some cases it doesn’t work; the title track sounds like three separate songs grafted together: an up-tempo rapped verse laid over a tautly wound bass line slams into an ascendant, slower chorus and a dub-step diversion. Perhaps that’s the hydralike production work of hit-makers Dr. Luke, Cirkut, and Max Martin in action? Fellow kingmaker Benny Blanco joins the crowded creative conference call on first single “Die Young” to much better results. There’s still a somewhat distended feel to the progression between parts here — a strummed acoustic verse arrives at an electro-house chorus — but it’s a more seamless blend.
