Forecasters suggest the album could sell 260,000-280,000 copies in the week ending Dec. 22.

Beyonce's self-titled album is aiming for a second week atop the Billboard 200 chart, according to industry forecasters.

The set debuted atop the Billboard 200 chart this week with 617,000 sold in the week ending Dec. 15, according to Nielsen SoundScan. Label sources suggest it could sell another 260,000 to 280,000 in the week ending Dec. 22.

The new Billboard 200's top 10 will be revealed on Thursday, Dec. 26.

Beyonce Tops Billboard 200, R. Kelly and Childish Gambino Debut in Top 10

That second-week sales sum would include physical CD copies of the album, as well as digital downloads from other retailers outside of iTunes. The album bowed exclusively in the iTunes Store on Dec. 13, and debuted atop the chart this week after only three days on sale.

iTunes is the only seller of the album through Dec. 18. The physical version of the album should start to reach U.S. retailers sometime between Dec. 18 and 20. (The arrival day varies, depending on how far -- and fast -- the CDs travel from the distribution center to retailers.)

'Beyonce' Already No. 24 Biggest-Selling Album of 2013

If "Beyonce" sells 260,000 in its second frame, that would bring its cumulative total to 877,000 -- making it among the top 20 biggest-selling albums of 2013. It's currently ranked No. 24 on the year's best-seller list.

The highest new entry on next week's chart will likely be B.o.B's "Underground Luxury," with perhaps 35,000 sold.
