DONT YOU GET IT!!
It's purposely awful on most of Recovery and post-Recovery because he likes to change it.
He realised how perfect it was on his first few albums and realized that he changes on every album so had to change it on Encore to a zombie-like monotonous flow to show how he'd changed. This was nothing to do with "drugs" as people say, he was taking drugs on his first few albums, it's cus he didn't want people getting bored of a PERFECT flow.
On Relapse, he had to change it from Encore, so made it pretty decent, but not monotous. He didn't wanna make it perfect cus then it would be like his first 3 albums and he wouldn't have developed as an artist right???
Then on Recovery he realised people would be bored of a pretty decent flow so he made it really bad instead. He didn't make it monotonous or zombie-like or perfect or pretty decent because he didn't want people getting bored and didn't want it sounding like his other albums, right?.
Remember guyz he has MATURED (like the mature use of 'slut' on Cold Wind Blows).
So next time you complain about Eminemz flow make sure you REMEMBER IT'S PURPOSELY BAD BECAUSE EMINEM CHANGES IT EVERY ALBUM.
He delevops like that and is more mature as he has a daughter now.
LISTEN TO NOT AFRAIDZ YOU WILL GET IT - "TO MY FANS I NEVER LET YOU DOWN AGAIN"HE WILL NEVER GIVE US A PRETTY DECENT FLOW AGAIN BECAUSE GOOD ARTISTS DONT DO DAT RIGHT???????
NEXT ALBUM HIS FLOW WILL BE ANYTHING THAT'S NOT PERFECT, MONOTONOUS, PRETTY DECENT OR REALLY BAD.
