HITS estimates: Cook 108.6k, Arch 68.2k

In a traditionally healthy week for album sales, David Cook saw his album plummet while David Archuleta saw his rise modestly according to HITS Daily Double's estimates released today. Cook's self-titled major label debut fell #3-10, down 62% from last week's take with 108.6k copies.

Although this might seem alarming considering the week is supposed to be extremely healthy for music sales in general, the drop is in line with second-week drops of similarly large releases. To put it into perspective, Beyonce's I Am...Sasha Fierce dropped 50% from its opening last week, while Nickelback's Dark Horse decreased by 47%.

Arch on the other hand saw a slight increase in his debut album's take according to estimates, as David Archuleta rose 8% to 68.2k copies, placing it at #18 for the week.

Although both Carrie Underwood's Carnival Ride and Jennifer Hudson's self-titled album appeared on the building sales chart before the final update, neither was able to finish in the Top 50.

Finalized figures from Billboard should be out by tomorrow night.
