There's a song by Outsidaz called "Money" that has the "I need money money money" line a couple of times.
Don't know about the hip-hop-language-like other one (don't even know what it means *g*)
Have a listen: http://www.youtube.com/watch?v=-FQAp4hAxiI
I believe there were more than 1. They were both articulate, had very good flows to their raps, and like I said had the words "I need money money money" in between the verses. As the last part of the chorus after "I need money money money," I someone else said "I need moolah, y'all."
There was a bit of brass in the background at some parts towards the end of the verses, if I remember correctly.
Judging from the amount of time I've tried finding a song with lyrics even remotely similar to these in Google, it must be a VERY underground rap song.
