If what you said is true. That is a horrible excuse to complain about the rap music today.
Forums like this give people a platform to discuss all kinds of albums. For example, there was a big ass thread on Lil Ugly Mane, another thread on the hottest up and coming MC's in NY etc etc.
I think that it just boils down to age so sometimes a lot of cats are stuck in the 90s or the 90s sound and their ears won't allow them to open up to music of today. The generational gap has become somewhat of a barrier
True about the forums, however it's still a limited pool of the population. When 2pac was hot for instance, you could talk about 2pac tracks with rap fans in Europe, Asia, everybody was listening to the same person who was making club tracks, thug tracks, political tracks etc. Remember this was pre-interent and social media era, so it is crazy when you think about it. There was also that element of "the struggle" in rap that popularized it in areas of the world where conflict was rife, such as in Africa, Middle East, Eastern Europe etc., people were bonding with the artist on an emotional level based on the contents of the songs. Each rapper came out with a "story" and people were connecting with it. Nas had the street tales, Jay z the hustler tales, etc.
The same cannot be said today about what rappers come out with, it's usually the same club shyt. So it is that part that puts some people off more than the newer "sound" so to speak. People may be a Chief Keef fan, French Montana or any of these new cats, but you won't see them rocking t-shirts of these artists the way people did in the 90s in places very far from America, and a lot of the fans won't be as familiar with their rappers discography as people back then were. This is because rappers nowadays are more like temporary trends and don't have the longevity artists had back in the 90s, back then if you had one successful album you could expect your second one to be successful too, nowadays your single is what you are depending on, which doesn't guarantee your album will be hot. Technology also influenced this too, so it isn't just the quality of the artists music itself that caused this effect. However you are right, some cats won't even give new artists a chance because they too attached to the 90s sound.
