Industry sources suggest that White's solo debut album may sell between 100,000 to 120,000 copies by the end of the tracking week on Sunday, April 29. Either Adele's "21" or Lionel Richie's "Tuskegee" will end up in the No. 2 slot.

The new Billboard 200 chart's top 10 will be revealed on the morning of Wednesday, May 2.

Country singer Lee Brice might be the second-highest debut next week with his sophomore album "Hard 2 Love." The set, which includes his recent No. 1 Country Songs hit "A Woman Like You," may sell around 35,000 to 45,000 copies.

On course for about the same start is British vocal group the Wanted, with its self-titled U.S. debut. The effort is led by the smash No. 3 Billboard Hot 100 single "Glad You Came." The act will be the second new U.K. group to bow in the top 10 this year, following One Direction. The latter saw its "Up All Night" debut at No. 1 with 176,000 sold according to Nielsen SoundScan on the chart dated March 31.

The third-best bow may come from Kip Moore with his debut album "Up All Night," with around 30,000 to 35,000. The set's single "Somethin' 'Bout a Truck" broke into the top 10 on the Country Songs chart this week, rising 11-9 in its 29th week on the tally.

On Nielsen SoundScan's Building chart (below), White is No. 1 while Adele and Richie are at Nos. 2 and 3, respectively. The Building tally is a precursor to the final Billboard 200 ranking -- reflecting the first four days (Monday through Thursday) of SoundScan's tracking week as reported by six major merchants.

As for the rest of the Building Chart: Brice is at No. 4 while One Direction's "Up All Night" is No. 5. Right behind 1D is Moore's "Up All Night," followed by the Wanted's self-titled set at No. 7. Jason Mraz's "Love is a Four Letter Word" is No. 8, Nicki Minaj's "Pink Friday: Roman Reloaded" is No. 9 and Josh Abbott Band's new "Small Town Family Dream" is No. 10.
