Ariana Grande's 'Problem' debuts at #3 on the Hot 100...

Ariana Grande's 'Problem' will earn her a spot in the history books when it lands the eighth-biggest debut ever on the Billboard Digital Songs chart this week.

The Iggy Azalea-assisted cut debuts at #3 on the Billboard Hot 100 after moving 438,000 copies, for the biggest chart debut of the year. It is also the best first week for a song on that chart since Katy Perry’s 'Roar' shifted 557,000 in August. She's certainly creating big problems for her chart rivals. Kudos to her for jumping on that promo as quickly as possible.
