Black Sabbath, 'Paranoid'
For more than 40 years, Paranoid has been perfect for a miserable, rainy afternoon – just you and your dragon-shaped bong. One of the greatest heavy metal albums ever made, with one of the oddest covers (a war pig!), it features such lumbering metal classics as "Iron Man," "War Pigs" and "Fairies Wear Boots," written while Ozzy Osbourne and Geezer Butler were reportedly high as monkeys. And then there's the title, that sad side effect of too many such afternoons.
