I Put a Spell on You was written and first recorded by Screamin' Jay Hawkins in 1956, becoming his signature song despite its theatrical shock rock style. Nina Simone recorded a celebrated version in 1965, and the song has been covered many times since in blues, rock and jazz. A new generation met it through Hocus Pocus in 1993, where Winifred Sanderson performs a bewitching version at a Halloween party. Online, that mix of blues classic and witchy pop culture keeps the hook circulating every October and in magic themed edits year round.
