If I had to bet I would bet Drake didn't write it or had a LOT of help.
How could a reference track be proven that it's not Daylyt recording it now? Also, even if it was, Drakes fans just mostly like his sh1t because it's catchy and they want to be him, and so wouldn't care that much. To truly Ja Rule him Kendrick probably needs some gay or pedo sh1t.
