Bob Marley, 36 Years Old
The Jamaican singer/songwriter was one of the driving forces behind the reggae genre. Bob Marley and the Wailers released their single "One Love/People Get Ready" in 1965, and the song skyrocketed to the top 5 on worldwide charts. He transitioned from reggae into a more free-flowing playing style when he found Rastafarianism. He died from a cancerous melanoma at the age of 36.
