It’s not hip hop you moron. https://imgur.com/gallery/zTdw7sF

All I have to say is " This is not Hip-hop",horrible use for a tag.

I'm fairly certain this is NOT hip hop.

Fantastic! Totally enjoyed it.

This would be house music, not hip hop.

My non technical definition of a "riff" would be anything piece or part of a song that digs into your skull and will not go away. It's the part of the song that when you hear it makes you say Hell Yea! and go scrambling for the volume knob.
The riffs haven't disappeared over the last 10 years they just don't reside on the radio dial anymore. It's not hip hop(that was 20 years ago) that drove them into hiding it's "core" music. You know metalcore, mallcore, emocore, breakdowncore, whatever you want to call it. That coupled with corporate run radio have driving anything with heart deep down into the underground. So you have to look a little harder for it. It's there. Examples? Ok
From the last 10 years:
High On Fire-Hung,Drawn and Quarter(they also just put out a new album that is so rifftastic it's scarey)
Kylesa-Time will Fuse It's Worth(whole album)
Tragedy-The Point Of No Return(The acoustic part give way to the brutality)
Hellshock-Your World(awesome!)
Grand Magus, Fu Manchu, Down, Nebula all have a Sabbath like vibe to them and they are all current along with a literal ton of others in that vein. And they all have no shortage of riffs.
Not to mention the myriads of old bands still in service, Iron Maiden, Judas Priest, Morbid Angel, Entombed(total riff band), the new Voivod rules, ect.
It's there I promise you just have to accept the riffs they offer as your personal savior and all will be right. Now go in peace and don't forget to feel it when you listen because if you don't feel it then you are just wasting your time.
