Rascal Flatts looks to be the next country act to top the album chart. The trio's "Unstoppable" is slated to sell up to 340,000 in it first week giving it a handy lead over its closest competitor, rapper Jada Kiss's "The Last Kiss."  Should Rascal Flatts stay on track, the group will score the second highest opening week in 2009 behind U2.

The soundtrack to "Hannah Montana: The Movie" will bounce up to No. 3, bolstered by the film's opening this weekend, according to Hits Daily Double. Hits uses a different chart methodology than Billboard, which relies on Nielsen SoundScan, but the two usually resemble each other.

Country crooner Jason Aldean should bow at No. 4, while fellow country singer Keith Urban drops to No. 6. Prince, who topped Hits chart last week (as opposed to Urban, who topped the Billboard 200), moves to No. 5. Taylor Swift starts to inch back up the chart at No. 8. I believe she may hit No. 1 again before this album is done.

We'll have the results of the actual chart Wednesday morning.
