That Adele reign just won't stop. The diva's "21" album could return to No. 1 on the Billboard 200 chart next week, so say industry sources. Those in the know suggest the set will sell over 70,000 copies by week's end on Sunday, June 10 -- enough to secure the top slot.

The new Billboard 200 chart's top 10 will be revealed on the morning of Wednesday, June 13.

If "21" returns to No. 1, it will mark the longest run at No. 1 since Prince and the Revolution's "Purple Rain" soundtrack also spent 24 weeks at the top in 1984 and 1985. Additionally, "21" would become one of only eight albums to rack up six months atop the list.

Sales are up a bit for "21" this week thanks to NBC's hour-long prime time special, "Adele Live In London," which aired on the night of Sunday, June 3.

The highest debut next week will likely come from country king Alan Jackson with his "30 Miles West" album. It may sell in the range of 60,000 to 70,000. His last studio effort, 2010's "Freight Train," rolled in at No. 7 with 72,000 sold in its first week according to Nielsen SoundScan.

The Beach Boys' new "That's Why God Made the Radio" will perhaps give the legendary act its highest debut ever and first top 10 album since 1976. The album is on course for a start in the range of 60,000 to 65,000 and should easily become the group's first top 10 since 1976's "15 Big Ones" hit No. 8.

Other albums due to make notable debuts next week include Curren$y's "Stoned Immaculate," Big K.R.I.T.'s "Live From the Underground" and Brandi Carlile's "Bear Creek."
