Do you think his music would have taken a different trajectory if he was on def jam?
Absolutely.
Look at Drake.
I think Stunna was just whoring him out to whatever could make money...Plus the drugs etc

had him trying to play guitar
Drake has more label approved creative license than any other major artist right now.
More than Beyonce. hov. Ye. etc.
all of them.
Even Eminem.
Drake can drop a soundcloud freestyle or freebie and have it end up on radio mix-shows around the fukking world in under a day.
Thats. POWER.
And that came because Drake had the license to truly be as creative as he wants. He damn near invented a lane thats probably beaten to death now (not saying he wasn't influenced himself).
You think any other major artist could drop all that free experimental shyt AND invest in all those other artists drake has? I mean not to mention he's discovered and endorsed more success in other artists than anyone else in recent history.
Read this interview when Take Care came out:

That album would have never dropped anywhere else.
