The charts are still primarily based on sales, but 10 digital track sales from an album will equate to one equivalent album sale (TEA), and 1,500 on-demand song streams from an album will be equivalent to one album sale (SEA). Sales and streaming data is compiled by Nielsen Music. Billboard will also continue to publish pure album sales charts for the above genres using Nielsen’s sales data exclusively.
By moving to a “consumption” methodology, Billboard is trying to make sure that the top-ranked titles each week on the above charts align with the top titles of those genres on the Billboard 200.
The on-demand subscription services that provide the data for the charts are Spotify, Apple Music, Tidal, Amazon Music, Soundcloud, Slacker, Napster, Google Play, Groove Music and Medianet.
