Donovan: Wear Your Love Like Heaven
[purchase]
Donovan's dreamy psychedelic folk rock doesn't age that well - this 43 year old hit single, for example, has a retro, slightly sluggish feel in a world of crisp pop production. But it's still sunny enough to fit nicely on the odd folk-and-then-some mixtape. And it made for a great moment in Season 13 of the Simpsons, where it served as soundtrack to Homer's experiment with medical marijuana.
