Week of Feb. 21

As predicted last week, a bunch of songs sprint up the charts this week, as songs by Paul McCartney, Norah Jones and Lady GaGa, among others, that had held them back tumble as many as 20 positions this week. Don't feel too bad for GaGa, as she has one of the nine songs that move up 5 or more positions, with her duet with Elton John -- the medley of "Poker Face," "Speechless" and "Your Song" from the Grammy Awards -- leaping 17-10.

While Elton makes chart waves, it's a newcomer from Britain that has the week's biggest mover. V.V. Brown released "Shark in the Water" last summer in her homeland, but iTunes named it its free download of the week just a couple of weeks back. That song leaps 36-14 in its second week, a good indicator that it could hit No. 1 in a few weeks.

Another big chart mover is the remake of "We Are the World," this time a relief effort for Haiti. It debuts at No. 25. The original "We Are the World" crashed onto the survey (then a Top 25) at No. 11 back the week of March 17, 1985. It eventually went to No. 1 for four weeks and became the No. 1 song of 1985. We'll have to wait and see whether this version does as well. Meanwhile, the current No. 1 song -- "Put It in a Love Song" by Alicia Keys and Beyonce -- spends its fourth week at the top, which gives it an early bid for 2010's top record.

"We Are the World 25" isn't the only Haiti relief song in the countdown, nor the only big mover. Rihanna's remake of Bob Marley's "Redemption Song" strides 24-18, while the remake of "Lean on Me" by Sheryl Crow, Kid Rock and Keith Urban jumps 32-21.
