Well, tell him how you would make a beat, then, someone. Come on... he's learning, this isn't the time for some bullshit negative talk.
Here's what I recommend: you seem to be good at cutting up the songs you want to sample. And that's cool, that's a great skill. But you are only using, as best I can tell, one song and that's it.
So, alright, check this out: it's basically something I heard of only today, it's pretty barebones. I don't know if it's actually a finished product or not, but it doesn't matter, it'll show what I'm talking about

He isolated the horn sample from a song. He put in some "la musica de Harry Fraud" vocal on it and wrote a beat (I'm pretty sure he wrote the beat).
This last bit is important, he wrote the beat out, so he can control it. What you've got is only whatever the drummer did on the song, and that's cool, but Harry here wrote the beat out, so when he wants to add intensity, he can put in another instrument (listen for when the shakers come in). There's not much going on in this song, just a looped horn and the beat changes and adds color and excitement to it.
You can also time stretch samples so that they fit your beat. He probably did some of that here.
But my point is, if you isolate the samples from songs, and add them to a beat, then you have the ability to leave a lot of space for a vocalist. It's hard to do that as a composer, but it gets easier.
But what you've got going on here is a complete song just chopped up and rearranged... so there's no real room for anything else, because the musicians on the original tracks didn't see a need to leave any because they were either singing (the Curtis Mayfield) or it was a vamp between vocals (the other tune).
So what you want to do is, isolate a cool instrumental part, and put it to a beat of your own composition. And if you don't know how to compose beats- by which I mean instrumental percussion parts- then learn that. I can tell you some of it.
I hope this helps- I don't know where you are musically, but hopefully I can be of some assistance. Either way, keep at it.
