“Pookie” (2019) is Aya Nakamura at her most playful: she's tired of the people around her who talk too much, spread gossip and can't keep a secret — and of the guy who isn't serious. “Pookie” is her own word; fans read it as someone who blabs or snitches.
The song was a huge hit in France and abroad. Like most of her songs, it's built on short phrases, repeated, over a slow Afro-pop groove.
It's C1 because of the slang, not the speed. Learn the street words for gossips, liars and friends, and you'll hear how young people in Paris really talk.
