Pharrell Williams 'Happy' to lead Billboard Hot 100 for second week

There's yet another "Happy" week in store for Pharrell Williams and America: the peppy Despicable Me 2/G I R L track is spending a second week atop the Billboard Hot 100.

After a rousing Oscars performance and leading up to the release of G I R L, "Happy" gained a ton of momentum this week, according to Billboard. As it easily clinched the No. 1 spot again from Katy Perry's "Dark Horse," "Happy" made gains in radio airplay, streams and sales.

And its sales are notably impressive. For the second week in a row, "Happy" sold over 400k digital downloads, moving 413,000 copies over the last week.

There were no new debuts in the top 10 of the Hot 100 this week, meaning that it's all the same songs as last week's chart... just in slightly different spots.

Thus, it follows that "Dark Horse" falls at No. 2 for a second week, despite a controversial music video that dropped last Thursday (Feb. 20) that helped the song to lead the Streaming Chart, the sales and radio airplay helped bump Pharrell to the top.

The next two songs hold in their spots from last week, as well, with Jason Derulo's "Talk Dirty" and John Legend's "All Of Me" holding at Nos. 3 and 4, respectively.

A new riser, Bastille's "Pomeii," which reached a new peak, rounds out the top 5. "Pompeii" is followed by another peaking song Lorde's "Team," which rose to No. 6 this week.

The top 10 is filled out by: Beyoncé and Jay Z's "Drunk In Love" at No. 7, OneRepublic's "Counting Stars" at No. 8, A Great Big World & Christina Aguilera's "Say Something" at No. 9 and Pitbull and Ke$ha's "Timber" at 10.
