This level of raw rapping can only be reached by a top percentile of people sure, but what is the point of any rapper trying to reach it at the expense of coming off like you're "basically rambling"? Who wants to spectacularly ramble? Why?
This is a great exhibition of "how" to rap, with zero respect for the concept of "what" to rap. I feel like it's beneath him to act like he could get away with this. It's so technically precise that it's probably not possible to replace the words and cogently carry any type of overlying concept than "hey look at me rapping"...which is almost satirical.
When is a 3 point specialist ever the best player in the NBA? I mean the moral of basketball is scoring points, and they score the most points efficiently, so they should be considered the best right?
Just like the best raw rhymer is automatically the best MC (rap god) right? If the world worked that simply success wouldn't be success.
This isn't all specifically towards your post but just a lot of sentiment I've seen in this thread...
The issue isn't wether this type of "black out" track is valid, it's about whether the whole album would be like this. You apply this level of emceeing to story telling or other kinds of approach and you seemingly have a good album on the way. If the album leaks and he's doing this for 2 or 3 more tracks you have a point, but em has show he can do both, you can get a "deja vu" and on the same album as an exhibition track, it's about balance, which has yet you be seen.
