I can't do albums for most artists, so I'm just gonna do artists.
Wu Tang Clan - 36 Chambers, Tical, purple tape, the pillage, liquid swords, supreme clientele, forever, return to 36 chambers, golden arms, no said date
UGK - Everything up to Ridin Dirty. Trill is very good. Trill O.G. is shit. Sweet James is mostly shit.
8 Ball & MJG - Comin Out Hard is a top 5 overall album. I know that. Outside Lookin In and On Top of the World are also great. OTotW is another classic, 5 mic album imo.
Nas - Illmatic
Tribe - everything up through midnight marauders. everything after that is pretty garbage.
De La Soul - early shit, and Mosiac Thump vol. 1 I think that record is mad overlooked.
Mobb Deep - all that shit. I actually think Murda Muzik has the most good tracks of the Mobb albums, but Return of the Mac is the best album from the crew. Infamous has the two best songs, but it get's sleepy here and there. Yeah, I said it. Get Away is one of their best joints too. Get's overlooked. There's even a couple bangers on the G Unit album.
E-40 - Everything up to Hall of Game, then you gotta skip to Revenue Retrieven epic 4 disc master slapper. Throw Charlie Hustle in there too.
Geto Boys - all the GB albums. Especially. The Resurrection since it kinda goes unpraised for how good it is. The Diary. Other Face albums are ehh
OutKast - First three albums. Some of Stankonia. Sir Left Foot
Dr. Dre Inc - Chronic, Doggystyle, Dogg Food, 2001, Marshal Mathers LP, Get Rich or Die Tryin
50 Cent - Power of the Dollar. Top ten album
Spice 1 - Everything up to Black Bossalini. After that it gets sketchy.
2 Live Crew - I celebrate the entire catalog
Too Short - Everything up to Gettin' It.
Pac and Big - yeah, all of it.
Bone - Creepin and E1999. Art of War was OK, and Krayzie Bone double CD was good. Mixed aside from that. Oh, first Mo Thugs.
Extended Swisha House fam - Chamillionaire and Paul Wall. Slim Thug. early mixtape screwed stuff. classic.
Noreaga - NORE, Melvin Flynt the Hustla, God's Favorite, NOREaster
Goodie Mobb - First two albums. Both 5 mic classic.
Brotha Lynch Hung / black market - 24 Deep, Season of the Siccness, Setrippinbloccstyle, Best of Black Market
Jay Hov - Reasonable Doubt, Vol 1. Blueprint, Black Album. Some of Blueprint 2.
Kanye - College Dropout, Late Registration
No Limit - Down South Hustlers Bouncin' and Swingin' Tha Value Pak Compilation, Ice Cream Man, The Shocker, I'm Bout It soundtrack, first Kane and Abel, Young Bleed, Fiend, Mac, Mystical, C Murda, Mr. Serv On and Skull Duggery. All follow ups were not as good (haven't heard Mac's). Don't hate because Master P drives a Luis Vuitton helicopter.
Gangstarr - Moment of Truth. a top 10 album.
Redman - all. top ten rapper. all he does is make classics
Ice Cube - Everything except War.
DJ Quik - Safe and Sound is the only really boring one. Everything else is bangin.
DMX - first album was classic, but every album's got a classic joint on it.
Del - Brother George, No Need for Alarm, Deltron 3030
Talib Qweli - Reflection Eternal and Quality
M.O.P - BRRROOOOWWWNNNSVILLE HOME OF THE BRAVE PUT IN WORK TO THE STREET LIKE A SLAVE
Three 6 Mafia - Everything up to Chapter 2 was classic, after that it got sketchier as they went on. Chapter 2 is a banger though.
Luniz - Operation Stackola
