Fueled by the success of 'All About That Bass,' Trainor travels 3-1 on the tally. Plus, Lady Gaga and Tony Bennett enter in the top 20.

Meghan Trainor takes over as the top artist in the U.S., rising 3-1 on the Billboard Artist 100 chart.

The Artist 100 provides the first weekly ranking dedicated to measuring artist activity across Billboard's most influential charts, including the Billboard Hot 100 songs chart, Billboard 200 albums chart 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.

Meghan Trainor Tops Hot 100; Tove Lo, Clean Bandit Climb Into Top 10

As Epic Records signee Trainor's breakout debut hit "All About That Bass" leads the Billboard Hot 100 for a fourth week, digital track sales account for 53 percent of her Artist 100 points. Radio airplay (19 percent), streaming (17 percent) and album sales (10 percent) follow. The release of Trainor's introductory EP Title has helped her reach the Artist 100 summit; it's spent its first three weeks in the Billboard 200's top 25, selling 55,000 copies, according to Nielsen SoundScan.

Below Trainor on the Artist 100, Kenny Chesney rockets 56-2, powered by the debut of his album The Big Revival at No. 2 on the Billboard 200 with 130,000 sold. Album sales account for 88 percent of his Artist 100 points sum (which boasts an overall 462 percent increase from last week).

Taylor Swift (4-3), Barbra Streisand (2-4) and Maroon 5 (5-5) round out the Artist 100 top five.

Tony Bennett & Lady Gaga's 'Cheek To Cheek' Debuts at No. 1

The Billboard 200's new leaders, Lady Gaga and Tony Bennett, launch at Nos. 15 and 17, respectively, on the Artist 100. With their jazzy collaborative Cheek to Cheek starting with 131,000 sold, Gaga and Bennett split artist points for the set and its duets on the Artist 100, since they're co-billed on the album. The former starts a better rank thanks largely to her higher profile in social metrics, as well as pockets of airplay, sales and streaming for her catalog of hit singles.

Meanwhile, three venerable folk/rock acts dent the Artist 100 for the first time, as they impact Top Rock Albums and infuse the Folk Albums chart's top three spots, respectively, with new releases: Leonard Cohen (No. 72), John Mellencamp (No. 84) and Tweedy (No. 90). Album sales account for all of each act's Artist 100 points.
