Due in dual parts to the quality of the music Plastic Little make and a sense of humour that has been lost in hip-hop in, like, forever. Plastic Little is some dope ass, funny ass shit. But it's not just the humor that sells Plastic Little, there is a biting critique of society at large and an acerbic wit and intelligence that comes with their brand of party music.
It's like 3 parts Shake your Ass and 4 parts F-You. A good combo, right? So while it may be party, drugs, drinks and bitches and all around fun (remember fun?) within their music on one level, there is a larger stew brewing under the surface, or a greater picture just behind the curtain or whatever. Pick which ever metaphor you prefer, dawg.
