Talk about impeccable timing. On the same day he announced the upcoming release of his second solo album, G I R L
, 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 galloped past Katy Perry's "Dark Horse"
 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.
