What do you mean by acquired taste, in what aspect of that song specifically? I have only heard parts of that album but from what I have heard, the theme sounds like Kool G Rap playing as the Don and Necro is the brutal enforcer/hitman.
Kool G Rap cannot be an acquired taste IMO, his lyrical abilities have been the backbone of many rappers that superseded him. Necro is one of them especially. If we are talking about Necro exclusively though then yes he would be an acquired taste as his concepts typically are dark and unforgiving in nature. Lyrically though, he is one of the illest.
