Help needed for recognizing some beats

[The Big V]

Here's the deal. A friend of mine claims he makes beats. But I found a beat he "made" in youtube , since then I dont really believe he is a beatmaker. Here are some of his beats , could you be so kind and try to recognize them and give me link from youtube or the site you've heard them? Im doing this cause I cant stand liars...

^That one really sounds like a rap song I heard before.. but then the rapping was removed. Dunno for sure though but I kinda recognized it immedately.

didnt jedi mind tricks rap over the first beat back in 2003 ?, not sure but i do remember this beat before
the others seem legit tho

I will check Jedi Mind Tricks from 2003 lilj , thanks

We are participating in a Talent Show and would be stupid to go out with stolen beats and pretend they are ours...

Perhaps try using Shazam on a few of those and see if it comes up with anything?

Okay I listened to all of the ones you posted but I can't really recall hearing them anywhere. Strangely, I do find them somehow familiar, :S
