Jedi Mind Tricks - Voilent By Design. Vinnie Paz is the most one dimensional embarassment that has ever been trumpeted as an underground savior, truly a hot garbage MC. But the album is an actual classic.
Beastie Boys - Paul's Boutique. Listen, the Beasties are cool and all but lets be real they are not good rappers, they are just good at making fun, listenable music and PB is one of the best Hip Hop albums ever released
Run DMC - Raising Hell. Don't crucify me, I know that Hip Hop was different then and they were good MC's for the time, but that nursery rhyme shyt hasn't been hot since '88, Kool Keith crushed those buildings.
Diamond D - Stunts Blunts and Hip Hop. Once again, another artist who knew how to make great music but his skills really were questionable
Dr. Dre - The Chronic. Dude has never written his own raps and doesn't even try and hide it, doesn't even make the ghost writers change their signature flow when doing songs for him
Akinyele - Vagina Diner. Great album, cult classic, but Akinyele is a comedy MC, no more no less
