Bob Marley, "Kaya" (1978)
Marley followed up 1977's landmark Exodus – an album focused on religion, politics and faith – with an album that was decidedly more laid-back in temperament. And nowhere was this more evident than on Kaya's title track, an ode to chasing away the rain (both literal and metaphorical) with a bit of the titular plant ("kaya," Marley once explained, is Jamaican slang for "herb"). Over a lilting rhythm, Marley essentially wakes and bakes, and before long declares that he is "feeling irie" (Rastafari for "good"). Why? "Because I have some kaya now."
