Here's my list of CLASSIC souther albums: (In Order)
Crooksters "Crooks N Our Own Way"
Playa Fly "Just Gettin It On"
Z-Ro "Look What You Did To Me"
Mr Sche "A Work Of Art"
Gangsta Pat "Deadly Verses"
Tommy Wright "On The Run"
K-Rino "K-Rino"
Playa G "Pimp Shit"
Kingpin Skinny Pimp "King Of Da Playaz Ball"
Master P "The Ghetto's Trying To Kill Me (OG version)"
Taylor Boyz "28 Gramz: Pure Dope"

My definition of "Classic" is more than 5 years old, and quality through out the whole album, which includes beats, and spits. Sorry I don't go for impact it made in the world of music, cause I really don't know.
