sorry didn't get back at you sooner, read the message and it was too late night to answer then forgot about it. I see you already have Chronic/Doggystyle which are the essentials. You can check out some of Cold187um productions, most notable Above the Law Black Mafia Life, Uncle Sams Curse and Kokane's Funk Upon a Rhyme. Dogg Pound's Dogg Food is pretty good too, although less on the "wee-hoo" g-funk sound. Alternatively you can also check out the related genre "Mobb Music" which is similar to g-funk... E-40 In a Major Way, Mac Mall, Mac Dre. Well pretty much stuff produced by Khayree.
There's no reason to not rate Crackspot or Three Bricks for Fushscale. Crackspot is an actual song, just because it's preceded by a skit doesn't mean it can't be rated. And Three Bricks is on every version of the album as far as I know.
Thank you!
