Meghan Trainor has knocked Taylor Swift out of the number one spot on the Billboard chart–a spot the ‘Shake It Off’ singer has held for 13 weeks–with the debut of her first album, ‘Title.’ The Artist 100 is the first weekly ranking dedicated to measuring artist activity across Billboard’s most influential charts.

According to Billboard, “this includes the Billboard Hot 100 songs chart, Top Album Sales, and the Social 50. The Artist 100 blends data measuring album and track sales, radio airplay, streaming and social media fan interaction to provide a weekly multi-dimensional ranking of artist popularity.”

It should be noted, however, that Meghan Trainor beat out Taylor Swift by a narrow margin.

‘Title’ is now said to be the strongest debut for a female pop artist since 2009, when the first album by Susan Boyle hit the Billboard charts.

Meghan Trainor, who is just 21, was recognized for her musical skills at an early age. Her official career was launched just last year, however, when ‘All About That Bass’ became a global sensation–going viral at first on YouTube.

In other Meghan Trainor news, the singer admitted recently that she and Harry Styles of One Direction recently collaborated on a love song. She chatted with Nick Grimshaw at BBC 1 on Tuesday about what may be to come.

“I wrote a song with Harry. It was unbelievable. He’s a very, very talented songwriter, I was very impressed. I was worried he’d just be a 20-year-old boy so I walked in with a prepared verse and chorus. He gave me very poetic, mature lyrics,” she said. “I was like, ‘Well, damn, Harry, you know what love is.’”

Trainor didn’t share word of when, where–or even if–the track will be released.

Right now Meghan Trainor is no doubt reeling in the sheer joy of ‘Title’ having debuted at the number one Billboard spot. How do you suppose Taylor Swift is feeling about that?
