He uploaded a set of royalty-free vocal samples. The pack included 3 construction kits and 7 songsets in styles such as R&B, Rock, Pop and "Old school".
I don't think this is what Rob had in mind when he put his vocals up on the internet for free use, but this is what CLAWED does to Rob. We bring you CLAWED Rob.
We'll be posting videos on YouTube soon.
Edit: All of the videos for the album are up on YouTube now. I hope you enjoy it!
