It's an unpopular opinion but I think it's Em's best album after The Eminem Show. IMO it's really a concept album and should be listened to with that in mind. This was the last time Em and Dre both felt super creative. I don't know how it was made, but it sounds like they locked themselves away and just made what the fukk they felt like making. Even though it has some misses it's maybe THE LEAST 'corporation/executive/record label fukking with the product' Em album I've ever heard.
Dre has some absolute bangers on there and I think he produced everything except for 1 or maybe 2 tracks, tops. And even though Em does the accents, this is the last time I remember him actually flowing seamlessly. He had ridiculous cadences and pockets, but he didn't sound like he was trying super hard to be a good rhymer. After Relapse, Em noticeably starts to work too hard and do too much to make crazy words rhyme.
