i'm agreeing with Nate Dogg but he never had his own cd...soo hell no
but DEFINITELY JADAKISS.Jadakiss has always been a monster,(monster is good) incaseyall not familiar witht he VA SLANG.. he is a monster,he is one of the best collab artists and freestylers... with DOUBLE R AND LOX...killer combination..

Fabolous also a hot collabo artist ,his track with ante dogg fire....

another is Busta rhymes..i dont care what anyones says but busta rhymes is one of the hottest collab rappers..think about it... most of the things he collabs on is hot... whether or not busta rhymes is hot by himself is somethign lse..but looks

at method man whats happenin??? hot
his verse in lumidee uhoh was hot..so was fab verse in it...hot
his own song with sean paul and spliff star....make it clap remix...hot
Pass the C...also a hot collab with busta,spliff and p.diddy..

these arent all exactly hot songs..but they are as party track they get you hype and that the idustry is based on gettin people happy and hype..why yall think lil john sodamn good and he cant even rapp...so overall i say busta rhymes is the best with collaborations.
