Chart Shakers

Susan discusses Usher's "Love in This Club," American 'Idols,' Janet Jackson and more!

GREATEST GAINERS: Adding sales to airplay can be like adding Mentos to Diet Coke. The resulting explosion has carried "Love in This Club" (LaFace) by Usher featuring Young Jeezy from 51-1 on The Billboard Hot 100. That's the third biggest jump to No. 1 in the almost 50-year history of the chart. The three biggest jumps are:

64-1: "Makes Me Wonder," Maroon 5 (May 5, 2007)
52-1: "A Moment Like This," Kelly Clarkson (Oct. 5, 2002)
51-1: "Love in This Club," Usher featuring Young Jeezy (March 15, 2008)

PACE SETTERS: As noted previously in this column, it's too early for a seventh season "American Idol" contestant to appear on a Billboard chart - that probably can't happen until a single is released by the winner (and the runner-up). But it's not too early for someone from the current group to have an influence on one of our charts. It happened two weeks ago when "Bohemian Rhapsody" by Queen returned to Hot Digital Songs after Michael Johns performed it on the show. This week, John Lennon's "Imagine" re-enters that same chart at No. 47 following a stunning performance by 17-year-old David Archuleta.

HOT SHOT DEBUTS: By the time David Archuleta does collect his first No. 1 on a Billboard chart - and does anyone doubt he will? - the "American Idol" franchise may be approaching its 200th chart-topper. Since I haven't reported the number in some time, you may have thought I stopped counting. But I didn't.

This week, Carrie Underwood's "All-American Girl" (Arista) advances 5-1 on Hot Country Songs. It's the fifth chart-topper for Carrie on this tally, and it's the 172nd No. 1 for the TV series, counting all national, domestic charts compiled by the Billboard Information Group. If you add up all the weeks those singles and albums have been No. 1, the total is now 677 weeks, many of which, of course, were concurrent. Here is an updated list of how many No. 1s each Idol has had to date:
