id say blend them, because trying to come out selling 100k or more units on the first week is over for rappers mostly. but the new lil nas x fella broke records for making a country style rap song. its not rapping rap because hes not spitting bars and it still have a country vibe to it. nelly was successful first at this with Tim McGraw and others too but I just think if you want to be successful in the music biz now, blend some songs to get on top of the charts
internet rappers way back in the 2000's on soundclick.com knew this by just uploading they're songs in other genre charts even if it didnt sound like that type of music and would just get the exposure until they took it down from #1 of the country or pop charts.
