The late Young Dolph spent countless hours recording in the studio -- and his upcoming posthumous album "Paper Route Frank" will bloom the fruits of the late Memphis rap star's labor.
Paper Route Empire fired off the latest single on Tuesday ... The O'Jays's sampling "Old Ways," irons out Dolph's persona to a tee.
Gucci Mane, 2 Chainz, Dolph's cousin and day one Key Glock, and PRE rappers Big Moochie Grape and SNUPE BANDZ all chime in for vocal contributions ... while Bandplay, Drumma Boy, Sosa 808, Dun Deal and others will hold down the production duties!!
