This week's Billboard Rock Songs chart again comes down to a battle between a California rap-rock sextet and an Ohio blues-rock duo. But they both may want to watch out for an upstart Kentucky unit that, for the second straight week, have the chart's highest climbing track.
10. Kings of Leon - "Radioactive"
Kings of Leon's first single from Come Around Sundown may have finally run out of steam. "Radioactive" drops three places this week, threatening to leave the Top 10 for the first time in almost four months.
9. Florence and The Machine - "Dog Days Are Over"
Florence and the Machine broke into the Top 10 at the beginning of the month with "Dog Days Are Over." The track reenters our chart this week, landing at No. 9.
8. Muse - "Undisclosed Desires"
"Undisclosed Desires" moves up one spot this week. The Muse cut has been as high as No. 7.
7. Mumford & Sons - "Little Lion Man"
Mumford & Sons got as high as No. 3 with "Little Lion Man," but in recent weeks they've been stuck on our chart's middle spots. This week the single is up one notch.
6. Neon Trees - "Animal"
"Animal" had been at No. 5 for five straight weeks. No longer: This week, the Neon Trees smash falls a spot.
5. Stone Sour - "Say You'll Haunt Me"
Audio Secrecy's first single drifts down one spot this week. "Say You'll Haunt Me" was one of 2010's best rock songs, but clearly people still want to hear it in 2011.

4. Three Days Grace - "World So Cold"
"World So Cold" peaked at No. 3, but this week the Three Days Grace tune is down a spot. The alt-metal quartet are the only Canadian group in our Top 10.
3. Cage the Elephant - "Shake Me Down"
Cage the Elephant are thundering up the chart, advancing three spots this week to No. 3. To promote their new album, Thank You Happy Birthday, the group played two songs on Late Show With David Letterman on January 11.
2. Linkin Park - "Waiting for the End"
"Waiting for the End" is at No. 2 for a fifth week, its hopes of taking the top spot still on hold. Linkin Park will start their North American tour on January 20.
1. The Black Keys - "Tighten Up"
The Black Keys appeared on The Colbert Report on January 11 in a pretty funny sketch where they demonstrated just how many of their songs have been used in commercials. One of those songs, "Tighten Up," is No. 1 for an eighth week on our chart.
