The track is written by Alicia Bognanno of the band Bully, and it has an infectious punk rhythm and cathartic lyrics. In context, it's a love song between these women, who have all seen Becky at her worst. But there's also something fatalistic in the lyrics as Becky wails, "Nothing's forever, this much I know, this much I know."
While Perry was inspired by the path of Guns N' Roses, the music of Her Smell takes cues from Bikini Kill and Hole. Bognanno wrote all of the tunes that are meant to be Something She and Becky originals, though over the course of the movie the band also performs covers, including the opener, The Only Ones' "Another Girl, Another Planet." But the fun, fast rock of Something She and the Akergirls stands in contrast to Keegan DeWitt's throbbing score, which adds a layer of dread to the experience of watching.
Becky's frequently described as a Courtney Love-type, but she's thoroughly her own beast. There are a million things to say about Moss' performance, which is without a doubt one of the most impressive you'll see this year. (Academy, get over yourselves and take fucking note.) But is not just that she's good at ranting and raving, spitting out Perry's bizarrely poetic dialogue that veers from prophesying to nursery rhymes. Becky is an entrancing trainwreck, seemingly aware of her Lady Macbeth qualities and leaning into them. Still, it's what Moss does in the final two sections, after Becky has gotten sober, that makes the whole of her work so amazing.
