Week of February 6

Songs make their way up the chart in a variety of ways. Take the two songs entering this week's Top 10. Jazmine Sullivan's "10 Seconds" has been a chart "sleeper," taking 10 weeks of mostly one- or two-notch moves before breaking through this week and sprinting 16-9. That becomes her first Top 10 since her No. 1 debut hit, "Bust Your Windows." Meanwhile, the Zac Brown Band's "Colder Weather" leaps 27-8 in its third chart week, making it all the likelier to become the group's third consecutive No. 1 hit. "Free" and "As She's Walking Away" (the latter with Alan Jackson) topped the chart last year.

Another of the big chart movers this week is the new No. 1 song. Cee-Lo Green's "Fool for You" jumps 7-1, the biggest leap to the top since Rie Sinclair and Friends' "My Confession" moved 9-1 a little more than a year ago. This makes Green's third consecutive chart-topper, following "Forget You" and "The Thrill Is Gone," his guest spot with Fantasia.

Sullivan and Green are part of a wave of adult R&B songs storming the chart. Joining that wave is Melanie Fiona's "Gone and Never Coming Back," moving 26-21. Fiona's former collaborators on last year's remake of "Wake Up Everybody," John Legend and the Roots, enter at No. 39 with "Our Generation (The Hope of the World)" from their iTunes Live release.

Also debuting are Darius Rucker's "Southern State of Mind" at No. 35, the third hit from his "Charleston SC 1966" album, and Michael Jackson with his second consecutive duet hit. "(I Can't Make It) Another Day," featuring Lenny Kravitz, is from "Michael," the same album that yielded his recent No. 1 duet with Akon, "Hold My Hand." This marks the first chart appearance for Kravitz since "I'll Be Waiting" went to No. 2 in 2007.
