Relapse was Eminem's prime and best album.
Yeah, I said it. The beats were unique, fluid and BUMPING. They had intricate instruments that you just don't hear on other albums. Dre really outdid himself on Relapse. Underground, My Mom, 3 AM, and Crack a Bottle are classic instrumentals.
The emotional songs were EMOTIONAL. Not forced or manufactured. If you don't hear the absolute raw pain in Em's voice on Beautiful and Deja Vu then you don't know pain and you don't know Em's true emotional songs. Deja Vu might just be his greatest song since the Eminem Show.
It's his rhyming prime. Hands down. The rhymes are so ridiculously intricate and fluid, it's mind-blowing. Yeah, he may use the accent to bend words a bit, but that just shows that he was looking to expand his art from the blocky sequences rappers get into.
See: 3 AM 3rd verse, SWA 2nd verse, My Mom 2nd verse, Underground entire song.
Variety: Serial Killer/Rapist, Name Dropping, Story Telling, Concepts, Emotion, Catchy, Raw. It has everything, yet it's not your typical Em album. It's refreshing.
It's what he wanted to do. Not pop because his fans cried for it. It's what he felt like doing in the booth, and you can tell because it's such an immense, artistic, beautiful final product. That's what Em is capable of doing. My mind's kind of wandering so I forgot a bunch of shit I wanted to say, but you get the jist.
