British singer Adele’s album "25" continues to stay atop of the Billboard 200 chart for five consecutive weeks.

Since its release on Nov 20, the album "25" has sold more than 7 million copies, making it the biggest selling album in the US for 2015.

The Billboard 200 albums chart is calculated via sales, track equivalent albums and streaming equivalent albums. Adele’s amazing chart performance is being driven by sales, which justifies her decision not to put the album on to streaming sites.

The album “25” is closely followed by Justin Bieber's "Purpose" and Chris Brown's "Royalty" on the Billboard 200 album chart.
