From his against-the-odds comeback to his first Billboard Hot 100 No. 1 hit, Justin Bieber is back and bigger than ever.
With 'Sorry' at No. 2 and prior hit 'What Do You Mean?' at No. 5, Biebs boasts simultaneous top five hits. Plus, Taylor Swift tallies a fourth Radio Songs No. 1 from '1989' with 'Wildest Dreams.'
