For fucking real man I feel you. Seems like RZA plays a major influence on Havoc. Cause Hell On Earth and OB4QL has VERY similar beats, specially Rainy Dayz.

Could of sworn that beat is produced by Havoc.

I think once Hav heard OB4QL he realized he needed to step up his sampling game up, which made him to pick out better samples for melodies, so in this case RZA was more experienced at the time and Hav took that as inspiration to step up his game and so he did on Hell On Earth. If you look back at The Infamous, it was released before OB4QL by a couple of months, and Hav's beats were a lot more old school/raw sounding, where as on Hell On Earth its like he stepped the fuck up by a mile. Flow wise, its easier to flow on Havoc's beats than RZA's beats, I mean Hav's drums are better. So I think melody wise they both got that shit on lock, but the drums is what it separates the two. OB4QL melodies > Hell On Earth melodies without a fucking doubt in mind. That album has the best melodies I've heard in my life on one project, damn did RZA get a good sleep before he started working on that shit!!
Man your making me feel like I'm living in the 90's now damn, bumps the fuck out of OB4QL.
