Pharrell’s ‘Happy’ No.1 Single In The US, Tops Billboard Hot 100

Pharrell has the number one song in the country.

Topping the Billboard Hot 100 Thursday, Pharrell's number one comes in the form of "Happy," a runaway hit featured on the Despicable Me 2 soundtrack and his soon to be released album, "G I R L."

Rising 2-1, unseating Katy Perry's hit single "Dark Horse," "Happy" is Pharrell's first Hot 100 chart-topper as a lead artist.

"Happy" joins "Drop It Like It's Hot" (Snoop Dogg), "Money Maker" (Ludacris), and "Blurred Lines" (Robin Thicke), all of which topped the chart with Pharrell as a featured artist.

"Happy" tops the Hot 100 fueled largely by a 22% gain to 402,000 downloads sold, according to Nielsen SoundScan, and leads Digital Songs for a second week. The sum marks the biggest sales week for a song outside the Christmas season since the week ending Sept. 15, 2013, when Miley Cyrus' "Wrecking Ball" crashed No. 1 with 477,000 sold (after the song's buzz-worthy video had debuted on Sept. 9)," reports Billboard. "Happy" additionally pushes 4-2 on Radio Songs with a 28% surge to 139 million all-format audience impressions, according to Nielsen BDS, and hikes 7-4 on Streaming Songs with 6.1 million U.S. streams (up 38%), according to BDS."

"Happy" is also number one the R&B/Hip-Hop Songs tally.

Pharrell's album, "G I R L," is due for release Monday. He is also due to perform during the Oscars (Academy Awards) this Sunday, March 2.
