On one hand, this video shows he does "borrow"...to say the least................a lot of phrases, and even quarter verses if not more from rappers...its very clear.
On the other hand, rappers have always used lines from past rap songs for newer generations. I can think of plenty of songs from the late 90s that had verses from the mid 80s rappers.
So in one way, you can say he is showing "respect" to these artists, by showcasing their lyrics. Some people will RECOGNIZE the lyrics were featured in a past song, HOWEVER some people will not, and they may see it is basically "jacking" rhymes.
The thing about Drake from this video anyway, is that he has literally OVERDONE this "borrowing" thing. Like I said, plenty of the greatest lyricists have done this, but I doubt they have done it to this extent. The other thing is that when rappers do repeat a line by another rapper, they will say something the way Kanye quoted, "Like 50 said, gone ahead and switch your style up, and if they hate, let them hate, and watch the money pile up". So they would at least reference where certain lyrics came from. Not all time, but many times. Drake doesn't appear to do that to many times in this video presentation.
Obviously, he has other writers as well, but at the end of the day, it is his voice. Playing the Devil's Advocate here: Maybe he thought that was part of his writing process, was to take people's lyrics and infuse them into his songs, and people would see it was part of his "style". Then again, maybe he's just being sheisty and stealing rhymes and hoping people won't recognize it. Drake McJacker (don't ask me how).
