gangster raps not dead, just rare. and if it WAS dead, someone could always revive it, its only music. we could bring back disco, funk, psychadelic rock, ect at any point we chose to. would it be the same? probably not, but thats because music reflects the energy and vibe of whats happening in the world around you, so if thats forced and unnatural, it wont be the same. but that doesnt necesarilly mean it will be bad music. my advice is to rap about whats really going on in the world around you, and if it happens to be gangster, then chances are people will relate. even if its not gangster, people will relate. just keep it real.
