Question: Which Canadian singer was originally featured on the song "Bankroll" by American DJ Diplo?
Sentence (from "Bankroll (song)"): Originally, Justin Bieber was featured on the song, but due to Bieber already having exclusives with DJ Khaled ("I'm the One") and David Guetta ("2U") at around the same time as Diplo released "Bankroll", Diplo was forced to remove the original from his SoundCloud account.
