2. Sweet Leaf - Black Sabbath (1971)
I love you, sweet leaf.
This classic hard-rock marijuana anthem, the lead track on Sabbath's third album, Master of Reality, opens with hacking cough. "Straight people don't know what you're about," sings Ozzy Osbourne. "Soon the world will love you, sweet leaf." How prescient of Sabbath to make such a prediction nearly 50 years ago. It's also considered the first stoner rock song. Covered by Alice in Chains, Ugly Kid Joe, Godsmack and Sacred Reich (1995).
