I Put A Spell On You, Words & Music by Jay Hawkins
Hawkins had originally intended to record "I Put a Spell on You" as a refined love song, a blues ballad. He reported, however, that the producer "brought in ribs and chicken and we came out with this weird version. I don't even remember making the record. Before, I was just a normal blues singer. I was just Jay Hawkins. It all sort of just fell in place. I found out I could do more destroying a song and screaming it to death."
"I Put a Spell on You" has been covered dozens of times, perhaps most famously by Nina Simone on the 1965 album I Put A Spell On You.
