I think it's QN5.
Tonedeff makes all around great music
PackFM spit the illest lyrics you've ever heard
CunninLynguists have chemistry that rivals Red and Meth
Session straight raw sound with hott ass lyrics
Mecca is a great song maker with a great charisma on the track
Kynfolk is the sound of the south while not sounding like all those other igna'nt ass crunk people.
Producer wise they are also stacked
Domingo has produced for the likes of: Eminem, Dialated Peoples, Angie Mar, Bone THugs, fat Joe, The High and Mighty, The Imfamous Mob, Immortal Technique, Kool G Rap, KRS One, Tony Touch and Tony Yayo.. you know the man's skills are crazy
Kno produced the acclaimed "White Albulum", one of the many remixes of the Black Album but not all of them were specifically requested by Black ALbum producers Just Blaze and 9th Wonder
Elite is a Ruff Ryder affiliate so he is up there.
These are just a few of the acts on QN5 Music. I don't think any one label themselve can top that. Some people may say Shady/Aftermath, but if you do, prove it. Here is my proof...
