Album sales will no longer be the definitive data used by Billboard to calculate its U.S. album chart.

According to The New York Times, Nielsen SoundScan—the organization which supplies the data for Billboard's charts—will begin including music streams in addition to album sales, beginning with the Dec. 13 chart.

Marking the chart's biggest change in over two decades, 1,500 streams of an artist's music on services such as Spotify or Rdio will count as one album sale. Additionally, 10 downloads of individual tracks (the equivalent of most U.S. albums) will also count towards the album chart formula.

The change should be welcome by many artists as well as a number of independent labels, many of which have made great strides in the streaming world but may not see six- or seven-figure sales weeks like Taylor Swift, the only artist to release a million-selling album this year (2 million sold as of this week).

Glassnote Records (Mumford & Sons, Childish Gambino) founder Daniel Glass said of his efforts pitching his artists to radio stations under the old chart formula: “I’ve been Scotch taping and Band-Aiding Shazam and Spotify, bringing in all this data for them. Now with this all-in-one streaming chart, it’s a much truer reflection of how much is being consumed.”
