Yeah I'd give it an 8 too I think. Basically no complaint other than the 3-4 filler tracks... the rest is fire. It was a necessary album to put Eminem back on top of the game, so to speak. But I don't think that album (Kamikaze) will be super relevant in a few years. People won't even know who all those people Eminem name-dropped are, aside from MGK who will probably remain infamously famous.
And the album is missing 1-2 radio singles. Lucky You is a hit, and there are a few other catchy tracks, but they're not real radio-singles like Eminem usually makes.
Now I think Eminem needs to take advantage of the buzz around him since Kamikaze and Killshot, and release another album in 2019. He can keep it short once again if needed, to make sure it's all fire. But he needs to make sure the album has 2-3 potential hit songs, some uplifting songs like Lose Yourself, Sing For The Moment, Till I Collapse, or even Not Afraid. Those are the tracks that stand the test of time and that everybody love. Of course they're not easy songs to top, but now is the best time to release more music like that. And Eminem should probably work with Dre for a couple tracks, now is the right time, not when he's 60 lol. When's the last time Dre actually produced a track that's available to the public?
