There's so much tbh. Context : born in the 80s and really started listening to HH during the 90s. But as a kid in Central Africa Republic first then in Europe, so pre-internet access was a real issue.
I don't think I've ever listened to a full De La, Brand Nubian, Ice Cube, Ice T, Pete Rock and CL Smooth, album. The only Tribe album I fully listened to is their last one, I've only listened to a couple Gangstarr albums (Moment of Truth and The Ownerz), but I did have that Full Clip compilation at some point.
I hardly know anything about the 90s Memphis scenes, same with the Bay Area, the whole "Crunk" era, a whole lot of big, older and new names I've never listened to a full album/mixtape (Lil Wayne, entire Dipset, Rick Ross, Jeezy, Wiz, Young Thug, Future, Drake, Nicki, Currensy, Travis Scott, Uzi, Vert, all those guys). Don't think I've ever listened to a full Roots album either tbh. Last Eminem album I've listened to is Encore. Not sure I've listened to a full Snoop album since Ego Trippin. I could go on and on. 50 last album I've listened to might actually be Get Rich lmao. Common I only listened to like 3 or 4 albums. I've even missed a couple GFK albums, post Fishscale basically. For decades the "West Coast" for me was just basically DR, Cypress/Soul Assassins and Warren G, basically until groups like Dilated of the Alkaholiks started making noise, later OF. Don't know nearly as much as I would of SpaceGhostPurpp and Raider Klan even though I love everything I've heard of them. Only Outkast albums I've listened to are ATliens and Speakerboxx/The Love Below (did listen to that Dungeon Fam album though).
Oh and I missed the entire Kendrick/Drake beef last year, only song I listened to is Not Like Us lol
