4. Kesha, 'Rainbow'
After her legal travails, anything Kesha released would have a veneer of triumph. But this comeback set, seven years since her debut, was an artistic warrior cry more potent than any might've expected. It began gently with "Bastards," an acoustic guitar-led anthem and instant lighters-up classic, pivoting into punk-pop (with Eagles of Death Metal) on the badass "Let 'Em Talk," in which she caps the line, "I've decided all the haters everywhere can suck my dick," with a cheek-pop. The gem-like moments keep coming, but the best is the sound of her cracking up mid-verse on the fist-pumping, Dap-Kings rocking "Woman" – it's the sound of someone who's survived a journey through hell knowing unquestionably she's stronger for it.
