Sample it to death

If you have a bang-up base material, your chances to fail in your way of using it are about 30%, while the other 70% promises some kind of success. It is possible, though, that your base material is still corking good and you manage not only to stick to the 70%, but also to use it in a way that your outcome can send you to hell and back. Three times.

I have an example of a situation like that. Let's take it from my beginning.

DJ EQ - Come on girl
I first listened to this track about 3 years ago in the Groove Delivery Sessions of Agent Stereo. Frenchy and all. I spent the whole summer of 2010 with it in my playlist and it kept coming back to me, until I found some other versions that step-by-step led me to the root. Listen to it here.

The Glue - Real good lovin'
I fell in love with the intro when I listened to it back in 2011. Had a more contemporary sound, slower tempo and the main synth melody immediately brought me back to mind the DJ EQ track. Listen to it here.

DeeJMD - Midnight cruise
Sounds more like DJ EQ's version with the french house feeling giving me the goosebumps all over again. This sucker reached my headphones towards the end of 2012, as I was searching soundcloud's shit. Listen to it here (with a free download).

And then it occured to me: who are all these people sampling?

Dope base material or what?
