KRS and Rakim definitely made music for the moment. Paid in Full and Criminal Minded were soundtracks to the times, and while the music has held up well, they haven't put out any high level material in a while. So if I really started to get into rap after the mid 90's, then I can understand it. Also, the thing is that rap music and hip-hop wasn't nearly as big as it became A.H. (after Hammer), so it's not like they were getting a lot of mass appeal everywhere.
