First off: Welcome to Audiokarma, AnzacSonata. Secondly, you posted some head-bobbing, trunk rattling, woofer-tearing classics. Eric B. and Rakim were simply ahead of their time - lyrically and sonically, no one east of the Mississippi was serving funk with such skill and dexterity as Erick and Parrish in the 80s/early 90s, and 2Live Crew introduced the rest of the nation to Miami-Dade's bone crushing bass. On the pop-rap front, even though I didn't appreciate them as a teen in the 80s, Tone-Loc and Young M.C.put out great releases while easing up on the profanity/explicitness whereas N.W.A./Eazy-E simply took the listener on a journey through Compton. Back east, P.E. threw S1W's in everyone's face and told them to "Fight the Power." Those are excellent picks and given that you're posting on AK, their presence on vinyl makes them all the more sweeter.
