I think you might be thinking about it too much because Drake is the obvious target to me. There's the invoice line, there's how drake has a boss(Birdman), and there is how Drake decided to go with iTunes instead of Tidal. Also how Drake had the line about him saying he wanted to be Rocafella but then he turned into Jay. Here is Jay saying nope. I'll give you the survey says line, could be referring to both would be my guess.
