No way it's a classic, I just don't see that happening. I'm sorry. If the metacritic score is close to MMLP or TES, don't let that fool you.
To me he has three classics that are pretty much untouchable.
CLASSICS: MMLP, SSLP, TES.
VERY GOOD: MMLP2
GOOD: REL, REC
DECENT: ENC, INFINITE
A classic is perfection. The worst song on SSLP IMO is My Fault, which is still a 6/10 song. The album has classic cuts like Guilty Conscience, Brain Damage, If I Had, 97 Bonnie & Clyde, Role Model, JDGAF, Rock Bottom, BME, SDGAF.
The worst track on MMLP is Under the Influence, which given the dope rhymes is still a 7-7.5 song. Album has classic cuts like Kill You, Stan, Way I Am, Marshall Mathers, I'm Back, Kim, Criminal, etc.
The worst track on TES is Drips, which is still a 6-7 song given Ems killer verse IMO. Album has cuts like White America, Business, Cleaning Out my Closet, Square Dance, Say Goodbye to Hollywood, SFTM, Superman, WTMS, TIC, MDGC, etc.
The worst tracks on MMLP2 are Survival and The Monster, which are IMO a 5 and 2-3 type songs. You don't see as many lows as Encore (Big Weenie, Ass Like That, Just Lose It, My First Single were fucking horrendous), Relapse (We Made You was horrible and there were so many meh tracks IMO), Recovery (Won't Back Down, You're Never Over, Love the Way You Lie). But you still have potentially classic Em cuts like Bad Guy, Brainless, Legacy, Headlights, Evil Twin, and other really good or great cuts like Rhyme or Reason, So Much Better, Rap God, So Far, Love Game, Baby, Groundhog Day, Wicked Ways, Desperation, etc.
Album is a 4 on your list, and I give it a 4/5 or 8/10. Could move up to 8.5 if some of the meh tracks like Asshole or Stronger Than I Was grow on me over time, or if some of the good tracks become even greater.
