Madonna
She has a ton of visually stunning videos that LEGIT pushed the limit, questioned stereotypes and constructs, and offered a hook/production that genuinely was never made solely for rado.
I miss this value a pop star would put into their sound and messages
They're ALL concerned with making WALMART yummies for the public, their pay check, and when they 'question constructs!' it's done in such a VMA-friendly style of tongue-in-cheek sexpop.. just a raunchy Jersey Shore vapidness.
Madonna did genuine think-pop sometimes.
