The Black Eyed Peas' new single, "Boom Boom Pow" (will.i.am/Interscope), will make a big boom on next week's singles charts.

Interscope is projecting the song, released on March 31, will sell more than 400,000 downloads in its first week, enabling a debut high atop the Hot Digital Songs chart.

That sum will likely propel the single to No. 1 on the Billboard Hot 100, giving the act its first chart-topper.

The group has charted nine singles on the tally, including "Boom," but has only gone as high as No. 3 (with both "Don't Phunk With My Heart" and "My Humps"). This week, "Boom" is at No. 39 on the Hot 100 based solely on its strong out-of-the-gate airplay.

Meanwhile, Keith Urban and Prince are both still in the hunt for a No. 1 debut on the Billboard 200 albums chart next week. Industry prognosticators suggest Urban's "Defying Gravity" (Capitol Nashville) could sell between 170,000-180,000, while Prince's Target-exclusive "LotusFlow3r" (NPG) may shift in the range of 160,000-170,000.

Those projections have grown since April 1, when the Urban album was forecast to move 150,000-160,000, while Prince was in the range of 140,000-150,000.

The new Billboard Hot 100 chart will be unveiled on April 9, while the new Billboard 200 albums chart will hit Billboard.com on April 8.
