Like most people have said, it's probably safest to assume that Daz produced it since in the Better Dayz booklet he is given credit, and I really doubt he wrote anything since he's a crummy rapper for the most part. But then again, we know how notorious they are for not always crediting the OG producers in some songs (like the ones Assassin did, yet his name is not in any of the books). But to me, the Street Fame OG sounds a lot more like a Hurt-M-Badd beat, or at least the bassline does... it definitely doesn't sound like a Daz beat to me.
