Taylor Swift is back at number one on the Billboard albums chart after just one week when One Direction bumped her from the top spot.
According to USA Today, the chart, which has been based solely on album sales since 1991, has begun incorporating streaming and digital track sales into its rankings. 10 digital track sales or 1,500 on-demand streams from an album count as one album sale under the new system.
As Swift’s 1989 ascended back to number one, last week’s top pick, One Direction’s Four, fell to fourth place.
Swift’s decision not to allow her music to be played on Spotify seems to have had little effect on her chart success.
