Only listened to like 4 minutes of it and all he's talking about is syllables and rhyme schemes, he sounds like that dude that be posting on here. He actually sounds like Cassidy, lol
He needs to expand his palate, rap skill doesn't = rhyming syllables. That was how I saw it too when I was like 17, lol...then I realized that most listeners don't care about or even notice that at all. You should incorporate it here and there if you're a reputable lyricist but there's plenty other things, like wordplay/voice/delivery/flows/subject matter/emotion/etc... that matter just as much as that when it comes to skills. I respect Eminem like crazy and how much he cares about the mechanics of rhyming but he needs to broaden his horizons, it would make him a better MC and a better song maker. Insane wordplay, to me, is like 10x more impressive and requires way more brainpower than internal rhyme patterns and doubles and all that
