great post ,now lets examine frank wilsons do i love ,it fooled the lot of us back in the day we never thought it was a motown track until it was uncoverded ,so to me anyway you can tell the difference between west coast and detroit tracks ,also the funks played on most detroit tracks out with motown ie ric tic/golden world/groovesville/revoilt etc and you put them up against any west coast recording at that time there tracks are rawer(?) than the polished west coast tracks .
