HITS estimates: Jennifer 27.6k, Cook 25.4k

For the first time in many weeks, David Cook was not the top-billed Idol alum represented on HITS Daily Double's Top 50 estimates.

It was Jennifer Hudson that took that distinction this week, as her debut album saw a 123% surge thanks to her showing at the Grammys. It sold 27.6k copies, sending it from #45-28. Cook's album also saw a healthy bounce, climbing 50% to 25.4k for a one-spot advance to #31.

Look for finalized figures to be released sometime in the next few days, hopefully sooner than later.
