ANOTHER SINGULAR FEAT FROM BIEBER

We've given you the macro on the remarkable, ongoing success story of Def Jam's Justin Bieber and Purpose; here's an update. Single "Love Yourself," which previously had been overshadowed by splashy smashes "What Do You Mean?" "Sorry" and "Where Are U Now," has knocked the mighty Adele's "Hello" from the top spot at iTunes.

Indicators suggest that the Ed Sheeran-penned "Love Yourself," now Top 15 at Pop radio, could be the biggest Bieber track yet. Stay tuned.
