Ridin Dirty By UGK - This is the seminal Southern album. Everything you know about southern hip hop stemmed from this album. Lil Wayne? Chamillionaire? T.I.? Big Krit? J.Cole...... everything outside of maybe outkast and Three 6 Mafia was profoundly affected by this album. There are so many overt references in modern hip hop to this album that there's no time to mention all the subtle ones
Doggystyle by Snoop Dogg - What I love about this album is that it's the quintessential idea of what a Mainstream hip hop album is. Its really the blueprint for making a mass appealing album. And he executed it to perfection. To those outside of the core hip hop fan base this album has everything outsiders LOVE and HATE about hip hop.
Reasonable Doubt - It had all the lyrical perfection of underground rap album but all the melody and deft song writing skill of a major release. You can play it in the background with a group of friends or you can listen to it with headphones brooding in your dorm room alone.
Blueprint - It was the cementing of Jay's legend but it was the launching of Kanye's legend. And while rarely put on the same level it launched Just Blaze's equally legendary status as well. It was dumbed down lyrics when you compare it to reasonable doubt BUT it was MILES upon MILES smarter then the rest of the albums that came out that decade
College Dropout. I can write for a decade about College Dropout. You can't talk about this album without understanding context. This was released in the Golden age of CRACK MUSIC!!! Like Biggie and others talked about moving coke in a mafioso way. They really didnt even talk about all the messy details. This was the age of TI and Jeezy and Game And Lil Wayne and Cassidy and FAB. It was the age of the grungy coke dealer standing on the corner moving rocks. Here comes Kanye in a Tight pink polo and turned the genre back on its feet. This album single handedly spawned artists like Drake, J.cole, Kendrick Lamar, Chance The Rapper, Kid Cudi, Wale, etc. These artists wouldn't even be marketable if it wasn't for this album.
So Far Gone by Drake - I wouldn't even call it his greatest work. However its patient zero for the type of music in rap today. Drake some how walked the tight rope of classic boastful, braggadocio rap about opulent lifestyles while making himself vulnerable and shamelessly talking about relationship failures almost as much as sexual successes. It really is the album for the millennial. Its very materialistic and shallow at times while maintaining the balance of being fun and entertaining. But it hides a sense of self doubt and vanity. It also doesn't touch on the harsh realities of the economy and social ills we were dealing with kind of like the news and TV we have in this age.
Good Kid Maad City - The perfect concept album. It was a concept without hitting you over the head with it. It was diverse yet very on topic. It was a recognizable storyline but it was never predictable. And it was the counter balance to So Far Gone. It was VERY socially aware. And while it was mainly written in a first person perspective. It was written in a way that everyone could identify. It sounded like a classic hip hop album from the golden era but it didn't sound tired or trite. It didn't sound like they purposely made the beats sound "gritty" or even "west coast" It was original production yet it all felt like it belonged in a different era.
Ready To Die by Biggie - It was hip hop poetry. Throughout the album Big raps and even brags and boasts about self destructive habits everyone could identify with, fear, or even aspire too. It was everything the average fan wanted in a rap album. Shameless killing, sex, and spending. Selling crack to pregnant women, revenge killing, and having sex with his main chick's sister.
Here's where he solidified his classic. He made good on the promise of his title. And showed the consequences of his self destructive album. The last song on the album. Arguably one of the best songs, he proved he was Ready To Die. It was also an ominous "Warning" to the path hip hop was really headed.
