Adele's '21' just returned to No. 1 on the Billboard 200 album chart for a 13th week, but it won't stay there long. Billboard reports that Coldplay's 'Mylo Xyloto' is on track for a huge debut in the No. 1 spot.

The site's industry insiders predict that the group's latest album, which hit stores on Monday, will sell in the neighborhood of 450,000 copies, which would make it the third-largest sales week for any album in 2011, behind Lady Gaga's 'Born This Way,' which sold 1.1 million in its first week, and Lil Wayne's 'Tha Carter IV,' which moved 964,000 copies.

'Mylo Xyloto' will be the band's third straight chart-topper, following in the footsteps of 'X&Y' and Viva La Vida Or Death and All His Friends.' Two tracks from 'Mylo' -- 'Every Teardrop is a Waterfall' and 'Paradise' -- have already appeared on the singles charts. You can read PopCrush's review of the album here.

Kelly Clarkson's latest effort, 'Stronger,' is on pace for a solid No. 2 debut, while Michael Buble's 'Christmas' looks like a good bet to hold down No. 3. Adele is likely to drop a few spots, while country singer Toby Keith will also have a Top 10 debut.
