My cheating days are over By Mike Nice and Marley Marl
http://www.zshare.net/audio/75268346f786be94/
This is a joint of Marley Marl’s second album “In control Vol. 2”. Like most people who owns either of this albums they were truly hit or miss and pretty much only remembered because of the classic Symphony tracks. However, I always liked this song and , as far as i know, Rich Nice was never heard from again. I could be wrong about that though cause with a name like “Mike Nice” he could have easily released like 15 albums and I would have missed it.
Phat Friend 
I am going to tentatively confirm because they both have production on a few of the same albums.
Looks like he might still be active according to reverbnation.
It’s Mike Nice.
This is his oeuvre:

Discogs is great for looking up what artists did [next]
And we have a winner!
Thanks…i’ll just make a little edit on that right now.
Speaking of discogs would you say yours is completely listed here? http://www.discogs.com/artist/Blockhead
