Sugarhill Gang: 8th Wonder [Sugarhill, 1981]
Although the Gang harmonize professionally enough to make you wonder what their gig was before they discovered talking, professional is as good as they get, and in the absence of vaguely interesting words the singing tracks are funktional dance music at best. The rap words aren't any more meaningful (this group never had better material than on its first, worst, and biggest single), but their rhythmic significance makes that irrelevant. You've heard of talking drums? Rappers are walking talking drums.
