While it seems that Adam Lambert is on the verge of his first No. 1 album on the Billboard 200 chart with "Trespassing," a number of other acts are set to debut in the top 20 next week.

Industry sources suggest that Lambert's "Trespassing" could sell around 70,000 to 80,000 copies by the end of the tracking week on Sunday, May 20. In a week without any other major new releases, and little competition, that may be enough to debut at No. 1 next week. Adele's "21" will likely be the runner-up, with between 60,000 to 70,000.

The new Billboard 200 chart's top 10 will be revealed on the morning of Wednesday, May 23.

Comedy rock duo Tenacious D (comprised of actors Jack Black and Kyle Glass) could see its "Rize of the Fenix" album bow in the top 10. The effort -- its first since 2006's "The Pick of Destiny" soundtrack -- could shift 40,000 to 50,000.

Also on tap for a possible top 10 bow is the latest "Glee" TV soundtrack. The Fox show's "Glee, the Music: Season Three - The Graduation Album" album could move around 40,000 to 50,000. That sort of sales figure will mark the lowest debut for a full-length "Glee" soundtrack album thus far. Of the 10 earlier full-length albums (not counting its live movie soundtrack), the lowest start was earned by the last one: "Glee, the Music: Season 3 - Volume 7." It began with 58,000 in December 2011 (according to Nielsen SoundScan).

Rock band Garbage has been absent from the Billboard 200 since 2007, but will finally make its return next week with the new studio set "Not Your Kind of People." The album is its first studio offering since 2005's "Bleed Like Me," and it is aiming for a launch of around 20,000.

On track to debut with perhaps a bit more than Garbage is Beach House's fourth studio album, "Bloom." Both Garbage and Beach House could flirt with a top 10 debut, but a top 20 start is more likely.

On Nielsen SoundScan's Building chart (below), Lambert is No. 1 while Adele's "21" is sitting pretty at No. 2. 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: Tenacious D is No. 3, Carrie Underwood's "Blown Away" is at No. 4 and the "Glee" set is No. 5. The "Now 42" compilation is in sixth place, Lionel Richie's "Tuskegee" is No. 7 and Garbage is No. 8. The "Smash" TV soundtrack is at No. 9 while Beach House's "Bloom" rounds out the list at No. 10.
