The iconic “Feeling Good” that Nina Simone turned into an industry standard with her interpretation off her landmark record I Put A Spell On You was released on June 1st, 1965. Not released as a single at its time, the track was used in a 1987 commercial for, oddly enough, fabric conditioner, and grew to great popularity. Later featured in a variety of cinematic and commerical soundtracks, “Feeling Good” arguably became Simone’s signature song, its pure optimism and soulful vocals blessing the ears of millions around the world.
