Pop songwriter Sarah Hudson brings emotional intensity to whatever she touches. Katy Perry's “Dark Horse” is a love song where danger lurks behind every synth stab and trap beat; Iggy Azalea's ominous, equally EDM-flavored “Black Widow” edges even deeper into obsessive passion and revenge sex. Hudson spells out her perspective on the acoustic-tinged “Naked Truth,” from her 2004 solo debut, sounding brutally honest and defiantly empowered.
