HITS estimates: 'Play On' #9 w/ 75.7k

There were good drops and bad drops to be had for Idol-related albums on HITS Daily Double's Top 50 building album sales chart.

Carrie Underwood led the pack with Play On, which was down only 34% despite the non-holiday sales week. The album held at #9 and sold an additional 75.7k copies.

Next up was Adam Lambert's For Your Entertainment, which suffered the largest decline among entries on the Top 50, surpassing drops experienced by fellow second-week albums Rihanna's Rated R (70%) and Lady Gaga's The Fame Monster (67%). Entertainment was down 18 spots to #21 and sold another 50.7k copies.

Re-entering the chart at #33 was David Archuleta's Christmas From the Heart, selling another 35.6k copies, while Allison Iraheta's Just Like You bowed one spot behind at #34 with 31.8k. My prediction was 35k so it was basically right in the range.

And Kris Allen rounded out Idol representation on the chart with his self-titled album at #47, down from #31 the previous week. It sold 22.7k copies, decreasing 35%.

Full sales numbers and chart positions courtesy of Billboard should be out by the end of the week.
