As previously reported, country star Jason Aldean is charging his way to a big debut on the Billboard 200 albums chart next week. Industry sources suggest the singer's "Night Train" is on course to shift around 400,000 (if not more) copies by the end of the tracking week on Sunday, Oct. 21. It will likely secure Aldean the second-largest debut of the year and his first No. 1 album.

The new Billboard 200 chart's top 10 will be revealed on the morning of Wednesday, Oct. 24.

R&B diva Brandy is on the comeback trail as her new "Two Eleven" is set for a top five start with perhaps 60,000 or so. Brandy's last studio release, 2008's "Human," started at No. 15 with 73,000 sold. She was last in the top 10 with 2004's "Afrodisiac," which debuted and peaked at No. 3 on the July 17, 2004 chart.

2011 "American Idol" winner Scott McCreery should also make a top five entry with his first holiday effort, "Christmas With Scott McCreery." It's aiming to bow with around 35,000. It'll mark the first new top 10 Christmas album of 2012.

Another album that's on track for a possible top 10 start is Jamey Johnson's "Living for a Song: A Tribute to Hank Cochrane." The album, saluting the famed country songwriter of such hits as "I Fall to Pieces," could sell around 25,000.

On Nielsen SoundScan's Building chart (below), Aldean's "Train" ranks at No. 1, followed by Brandy's "Two" (No. 2), Mumford & Sons' current No. 1, "Babel" (No. 3), McCreery's "Christmas" (No. 4) and Jamey Johnson's "Living" (No. 5).

As for the rest of the Building chart's top 10, P!nk's former topper "The Truth About Love" places at No. 6, followed by Anberlin's new "Vital" (No. 7), Miguel's "Kaleidoscope Dream" (No. 8), Macklemore and Ryan Lewis' "The Heist" (No. 9) and Little Big Town's "Tornado" (No. 10).
