Depending on your tastes, the Justin Bieber musical redemption continues along — this time, with a remix of Sage the Gemini's catchy "Rack City"–inspired "Gas Pedal," on which Bieb gets to sing and rap. Honestly? It's pretty great. Even his lyrics have that satisfying tinge of teen: "Gas pedal, gas pedal / Tryna stay up like Adderall / I ain't even stressin', no at all / So presidential, I'm federal." Bieber for Prez. Of Canada.
