as for dr dre for the last five years at least his main concern has been the sound and engineering of the tracks thats why his stuff is just simple but large,about ten snare samples in each drum hit or somethingand as for neptunes its known that theyll take an old record and just play over it,ie take the groove of it,then simplify the beat,and use preset sounds from sampler/sequencers to replace the original instrumentation.but yr chick still dance to it regardless init
