Depending on your tastes, the Justin Bieber musical redemption continues along — this time, with a remix of Sage the Gemini’s catchy “Rack Cityâ€â€“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.
