, Pharrell Williams will have plenty to celebrate after landing his latest #1 hit.

By now you've surely heard the "Despicable Me 2" smash "Happy," and clearly you like it because the song just keeps climbing the charts.

"Happy" To Be Here

After a few weeks of slow rise, the bouncy pop smash "Happy" finally [article id="1722185"]galloped past Katy Perry's "Dark Horse"[/article]
 to hop into the top spot on the Billboard Digital Songs chart. With sales up 31 percent to 329,000, the song easily took the lead, besting Perry's 277,000. It also snagged #1 on the iTunes chart and gave Skateboard P his first #1 as a lead artist in the nine-year history of the Digital Songs chart.

One of the week's biggest gainers was John Legend's "All of Me," which rose seven spots to #4, as sales grew 46 percent to 164,000. It was also a good week for Bastille, whose "Pompeii" broke into the top five for the first time at #5 (146,000).

"Frozen" And Beyoncé Hit Milestones

It was a big week for a pair of chart mainstays, as the soundtrack to animated smash "Frozen" moved another 100,000 copies to move past the 1 million mark in its third month on the charts. Just a few spots behind at #4, Beyoncé's self-titled pop-up album shifted another 48,000 to boost it's 10-week total to 1.75 million, pretty much ensuring that Queen Bey will hit the 2 million mark before spring.

Elsewhere, after a year and a half on the charts, Imagine Dragons' Night Visions continues to crush it, moving up six spots to #6 as sales climbed by 77 percent to 41,000. While an iTunes sale was part of the reason behind the bump, it was enough to boost the "Radioactive" rockers over the double-platinum plateau.

It was also a good week for Lorde's Pure Heroine, which shifted 38,000, putting the New Zealand singer a week away from platinum status. The week's biggest debut came from country bad boy Eric Church, who hit #1 with Outsiders on sales of 288,000.
