Green Day is a lock to come in at No. 1 on the album chart next Tuesday, the only question is what will the tally be? On one hand, its presumptive entry at the top spot is impressive because it will be accomplished with only three days of sales since "21st Century Breakdown" hit retail on Friday, May 15, instead of the traditional Tuesday release date. On the other hand, it speaks to how badly everything else is selling that "Breakdown" can come in mightily at No. 1 with basically one hand tied behind its back.

Based on very preliminary data, Hits Daily Double is predicting "Breakdown" will sell up to 300,000 copies. There are a few wildcards, among them that the title is not available at Wal-Mart because the band decided not to make a clean version available, so that knocks the CD out of the largest retailer.

As far as the rest of the top 10, the "Hannah Montana" soundtrack shows no signs of slowing down and should be in the No. 2 slot with around 60,000 units sold. The only other debut in the Top 10 in what was an exceptionally slow release week, looks to be rapper Cam'ron, whose 45,000-50,000 will land him a No. 3 spot.

Otherwise, our old friends Lady GaGa and Taylor Swift continue their six-month reigns at the top or near the top of the charts. Last week's leader, Chrisette Michele is predicted to fall to around No. 8 with sales of 25,000. Bob Dylan, who was on top two weeks ago, will likely move slightly more than Michele for No. 6 or No. 7 (vying for those spots with Rascal Flatts.
