A lot of rock bands snorted insane amounts of cocaine in the 1970s, but none of them wrote a song about the drug that was as brilliant (and as blatant) as Black Sabbath's 1972 track "Snowblind." "Feeling happy in my vein," Ozzy sang. "Icicles within my brain/ Cocaine." The song is ostensibly about the dangers of the drug, but nobody in the band had any intention of stopping for quite some time. On the album sleeve, the band even wrote, "We wish to thank the great COKE-Cola Company."
