I'm so surprised that Kurupt's album made your list. It wasn't that popular, but I love it too.
My top 5 would be filled with 2pac's albums, from All Eyez on me and Makaveli to even Better Dayz.
Outside of those, I couldn't pick 5, but let me try the top albums that I listened to the most (and very highly recommend) as a top..18?
The Last Emperor's Science Team...Go! and Palace of the Pretender
Boot Camp Clik's The Last Stand
Bronze Nazareth's Great Migration
Cilvaring's I
Exposition's The Metro
Capadonna's The PIllage
Kenn Starr's Starr Status
Kurupt & J.Wells Digital Smoke
Edu Leeds Mass Movements albums
Nas & Damian Marley's Distant Relatives
Raekwon's Cuban Linx (both albums)
Red Gone Wild
Doggystyle and 2001 by Snoop
Statik's Population Control
Digital Bullet by the Rza
The Handome Boy Modeling School's albums
Wu-Tang Forever.
In no order, lol. There's no way I could pick top 5, but the Last Emp, Boot Camp and Digital Smoke would surely make my personal list.
