Yeah he's always good for a few joints, but he's a far cry from the cat who made "MMLP". I think it's not so much just the yelling, but his delivery and flow often sounds stilted and force, like on "My Life". Like duke above said, when he spits the same tracks live they sound much better so I don't know why he can't capture that on record.
"Going Through Changes" and "Deja Vu" are two of my favourite Em track. I actually fukked with Relapse as well, it was a concept album and I understood it, plus Dre's production was flames.
Relapse would've been amazing if he just dropped the accent. I wish he didn't get so emotionally hurt over fans who said his accents were lame that he overcompensated by shouting all the time. Small steps Em, cmon...
