Going off on a short rant:
Here in Germany, we have a state-authorized collecting company on fees to musical rights called GEMA which pretty much makes most music on YouTube impossible to watch here as they demand much higher fees than the ads even make. They've been often critisized by users, companies and even artists as they want every piece of art by a major artist to be registered and its rights managed by them. But as artists most times don't upload music to YouTube to get the ad revenue, but to promote their songs, there's a major issue with YouTube not paying the fees because they would bleed money while the artists can't just say they are okay with lower fees as their music rights are managed by GEMA and... well, most mainstream music on YouTube is just outhright blocked for everyone with a german IP. There were a few lawsuits, but none came to an agreement that YouTube and the artists are OK with, so the consumers are just screwed in that regard. Many of the YouTube links in this thread don't work for us Germans, our only way of getting around that are proxies, but that of course is far from ideal.
Long story short: Sorry, can't help you tigerroast, I can't even watch the videos you linked. And even if I could, I have no idea about rap music
So instead I'll just post some music I like, eventhough I'm quite sure most people here won't enjoy it. First off is the French musician Igorrr. I have no idea what this style of music is called and don't care, it's just amazing:
Second, Austrian Black Metal band Harakiri For The Sky. Most music I listen to on a daily basis is some variant of metal or punk, and while this band for sure isn't even close to being one of the best black metal bands (whatever you define that as), I often get back to them. Especially since Ghost Bath signed of a record deal with Nuclear Blast, those guys destroyed so many bands it hurts my soul.
Toshiaki Sakoda hasn't done anything decent in the last 20 years or so (or if he has, it's not on YouTube), but his soundtrack of the PC-Engine game Devil's Crush is just pure genious in my opinion. Especially in the CD release:
