1. Snoop Dogg on Dr. Dre's "Nuthin' But A 'G' Thang" (1992)

Album: The Chronic
Producer: Dr. Dre
Label: Death Row

The diggy-diggy-doctor's G-Funk invasion wouldn't have been half as effective without the velvety drawl of a young Snoop Dogg. His contributions have all the makings of the now classic Doggfather formula—warnings against hoes, declarations of his prowess on the mic, and the obligatory spelling-out of his nom d' plume. Telling us that "perfection is perfected" seems a little superfluous, but that was probably just the indo smoke talking.
