If "21" returns to the top, it will mark the tenth non-consecutive week at No. 1 for the album. The British singer's set has yet to leave the top three positions of the chart since its debut on the list dated March 12 -- 15 weeks ago. It's still too early to tell how either Adele or Gaga will sell this week.
Next week's top debuts will come fromTech N9ne's"All 6's & 7's,"All Time Low's"Dirty Work" andRonnie Dunn'sself-titled solo debut. Industry sources suggest the former two might sell around 50,000 copies by week's end on June 12, while Dunn could shift 45,000 or so.
