Through the end of the year, Chart Beat is looking back at the biggest achievements on Billboard's charts in 2010.

From "Empire State of Mind" to "California Gurls," Lady Gaga to Lady Antebellum, B.o.B to "OMG," "Fearless" to "Not Afraid," Train to "Airplanes" (specifically, a "G6") let's recap the most impressive honors achieved on Billboard surveys this year.


Linkin Park's "The Catalyst" becomes the first track to debut at No. 1 on Rock Songs. The first single from "A Thousand Suns" eclipses the chart's previous highest-starting song, Pearl Jam's "The Fixer," which arrived at No. 2 in 2009 ...

Zac Brown Band
banks its fourth No. 1 on Country Songs, as "Free" rises 2-1. The new leader makes the group's album "The Foundation" the first major-label debut set to yield four No. 1s on the list since Brooks & Dunn's "Brand New Man" generated a quartet of toppers in 1991-92 ...

How likable is he? With a 2-1 lift on Dance/Club Play Songs for "I Like It," Enrique Iglesias collects his seventh No. 1 on the chart, equaling Michael Jackson and Prince for most leaders among male artists in the survey's history ...

After no solo male artists had arrived with a pair of career-opening No. 1s on Pop Songs between the chart's inception in 1992 and last year, two such singers have achieved the feat in 2010. Taio Cruz's "Dynamite" follows "Break Your Heart," featuring Ludacris, to the top after Jason Derulo had reigned with "Whatcha Say" and "In My Head" ...

John Mellencamp earns his 10th top 10 on the Billboard 200, as "No Better Than This" begins at No. 10. The set opens one week shy of the 28th anniversary of his first top 10 and sole No. 1, "American Fool," reaching the chart's summit.
