I think the concept of the song Move On by Slaughterhouse would be relevant to this forum. Motherfuckers move on!
Honestly, stop trying to live in the past, as some have said branching out is what keeps it fresh, he needs to keep himself motivated. Yes some of the beats are weak, but if you look at it this way, Relapse had good beats, but some of the lyrics on the songs were awful. My Mom for example. Beats aren't that important when Hip Hop is trying to regain its status, HTS had great beats, but the lyrics were what took centre stage. I miss the old shady, but thats it, old, Eminem still provides with a few songs now and again who bring back that nostalgia, but i think he's slowly spoon feeding us his transition.
I've noticed this with all artists these days, when they tweak their sound, their fans complain, but also when they were 'who they were' people still complained. We love to complain, a punch in the face to get you back to reality is what some people need, as sometimes nothing a person brings out will ever satisfy certain people.
