Adele's [1] "21" is on track to head back to No. 1 on the Billboard 200 albums chart next week, as this past Tuesday's crop of new releases aren't posing a threat to the British singer's return to the top.

According to industry sources, "21" may sell around 85,000 by week's end on Sunday, April 9. That would easily surpass the sales of the biggest release this week, rock band Hollywood Undead's [3] second album, "American Tragedy," which could sell perhaps 65,000.

This past week's No. 1, Britney Spears [5]' "Femme Fatale," will likely drop to the runner-up slot on the tally, though it's too early to tell what the album's second week total might be.

After Hollywood Undead, the next biggest arrival could be Asking Alexandra's "Reckless and Relentless," followed by the the new "Tron: Legacy Reconfigured" remix collection.
