scratch that, t-minus, 40, and boi-1da
best i ever had was drakes true first hit, produced by boi-1da. 40 and boi1da made ALL the good songs/hits off thank me later, 40 was the only dude on take care besides t minus and boi-1da who made headlines. Boi-1da also produced forever, one of drakes other tracks that put him on. 40 produced much of so far gone, including houstalantavegas time which was a big track for drake. He also made successful, another of drakes big breaks. Tminus and 40 produced im on one, arguably drakes biggest song. Boi-1da produced still fly as well, one of drakes earliest popular songs. Lastly, 40 and boi-1da virtually produced all of nwts, with the exception of dj dahi (wouldnt be surprised if he becomes a mainstay in drakes arsenal as well.)
The only works of drake that werent mainly produced by boi-1da 40 and t-minus were room for improvement and comeback season. They did have spots on those but only a few.
Needless to say, ALL of drakes hits were made by one of these three. I rest my case.
