-Signing to Shady Records (yelawolf failed but the man has potential imo, he had like 0 promo :X )
-Signing to Aftermath except if you are sure to become a famous artist (the label had like +40 artists and only a few albums in the industry are from Aftermath)
- that beef 50 cent vs Rick ross because Rick ross became popular which is a bad thing to me
- Soulja Boy rapping
- Signing SH (they sold too many copies even if they flopped
)- some guys leaking hip hop albums a few weeks before an official release

(some guys leaking bad songs which were supposed to stay in the bin
)- working for Jimmy Iovine when your artist name is Eminem ( even if we can find good points tbh)












(even if illmatic is a classic album so it couldn't be considered as a "mistake"
