Plus: Pentatonix aiming for its seventh top 10 album with "PTX, Vol. IV – Classics."

The Chainsmokers’ new album Memories… Do Not Open, is aiming to debut atop next week’s Billboard 200 chart, according to industry forecasters. Sources suggest the set -- which will mark the duo's first No. 1 -- could earn over 200,000 equivalent album units in the week ending April 13, with perhaps 150,000 to 160,000 in traditional album sales. Memories was released on April 7 through Disruptor/Columbia Records.

The Billboard 200 chart ranks the most popular albums of the week based on multi-metric consumption, which includes traditional album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA). The top 10 of the new April 29-dated Billboard 200 chart (where Memories will likely debut at No. 1) is scheduled to be revealed on Billboard’s websites on Sunday, April 16.

The hefty amount of the sales of Memories will be driven by a successful concert ticket/album bundle sale redemption promotion with the duo’s tour, which kicks off April 13 in Miami. The ticket/album offer was also included with select dates of the act’s residency at the XS Nightclub and Encore Beach Club in Las Vegas.

Memories is The Chainsmokers’ first full-length album, after releasing two EPs: 2016’s Collage, which peaked at No. 6 on the Billboard 200; and Bouquet, which hit No. 31 in January 2016, following its release the previous year.

Drake’s More Life, which is currently in its third straight week at No. 1 on the Billboard 200 (dated April 22), will likely fall to the No. 2 slot in its fourth week, behind The Chainsmokers.

Following The Chainsmokers, the chart’s next biggest debut will likely come from Pentatonix, as the vocal group’s PTX, Vol. IV – Classics, could start in the top five with around 50,000 units (most of which will be in traditional album sales).

The a cappella quintet previously hit the top 10 with A Pentatonix Christmas (No. 1 in January), its self-titled album (No. 1; 2015), That’s Christmas to Me (No. 2; 2014), PTX: Vol. III (No. 5; 2014), PTX: Vol. II (No. 10; 2013) and PTXmas (No. 7; 2013).
