26. Outkast, 'Aquemini'
The most famous songs on Outkast's third album – the singles "Rosa Parks" and "Skew It on the Bar-B" – are party tracks for passing the dutchie from coast to coast. But they're just part of what makes Aquemini such a red-eyed blast. Mind-erasing Southern-slacker funk suffuses the whole enterprise, from the water-pipe bubbles in the title track to cruising-the-streets soul of "West Savannah" and "Liberation" to the reggae flourishes on "SpottieOttieDopaliscious." They never sounded this smartly spaced-out again.
