Hayley Williams knows her depression meds as well as she does her heavy alternative rock scene history. In a recent interview with Water From Your Eyes’ Rachel Brown, the Paramore frontman even went as far to offer herself up as a spokesperson for the drug Mirtazapine. In the meantime, she’s doing its makers a solid for free — as well as brandishing her harder-edged musical influencers — on the single that homages the antidepressant. “Here come my genie in a screwcap bottle / To grant me temporary solace,” she sings over swerve-driving alternative rock cluster, popping and crushing shoegaze, grunge, and post-hardcore down into a single pill form. “I could never be without her / I had to write a song about her.” The way Williams lovingly desires her Mirtazapine, it might actually qualify as the one romantic constant in the Paramore frontwoman’s life that hasn’t let her down (both literally and metaphorically.)

Hayley Williams’ “Mirtazapine” single is available now on Post Atlantic.
