After their well-received live performances at the Academy Awards, broadcast on ABC on March 2, Pharrell Williams' "Happy" and Idina Menzel's "Let It Go," the latter of which won best original song honors, both shine on the Billboard Hot 100. The former leads the list for a third week, while the latter blasts into the top 10, vaulting 17-9.

After it led the Hot 100 for four weeks until two weeks ago, Katy Perry's "Dark Horse" spends a third week at No. 2. The track tops Streaming Songs for a fourth week, although with a 20% drop to 8.9 million streams. It slips 1-2 after eight weeks atop On-Demand Songs (2.7 million, down 6%). On Digital Songs, which it led for five weeks, "Horse" retreats 3-5 (182,000, down 14%). It holds at No. 2 on Radio Songs (153 million, up 1%), which it dominated for two weeks earlier this month.

With "Happy" up by 14% in overall Hot 100 points and "Horse" down by 12%, the former boasts a strongly widening 60% points lead.

Aside from Williams, Menzel and Perry in the Hot 100's upper ranks, John Legend's first Hot 100 top 10, "All of Me," rises 4-3. The piano ballad pushes 4-2 on Digital Songs (210,000, up 6%), 6-4 on Streaming Songs (5.7 million, up 9%) and 8-6 on Radio Songs (107 million, up 22%).

Jason Derulo's "Talk Dirty," featuring 2 Chainz, dips 3-4 on the Hot 100 after four weeks at its No. 3 highpoint. It rises to a new peak (9-8) on Radio Songs (93 million, up 7%). Bastille's "Pompeii" holds at No. 5 (and rules Hot Rock Songs for a fourth week), climbing 5-4 on Radio Songs (122 million, up 11%).

In the top 10's second half (aside from Menzel's ascent), Lorde's "Team" holds at its No. 6 peak; Beyonce's No. 2-peaking "Drunk in Love, featuring Jay Z, stays at No. 7; OneRepublic's No. 2 hit "Counting Stars" keeps at No. 8; and, Pitbull's former three-week No. 1 "Timber," featuring Ke$ha, is likewise a non-mover at No. 10.

"Happy" continues to be aptly titled for Pharrell Williams, as the song takes over a bevy of Billboard airplay charts. It crowns Pop Songs, Rhythmic Songs and R&B/Hip-Hop Airplay, while claiming Greatest Gainer honors on Adult Contemporary and Adult Pop Songs. (It also debuts, at No. 34, on the DJ-based Dance Club Songs survey.) "Happy" has ruled the airplay/sales/streaming-based Billboard Hot 100 for three weeks, while parent album "G I R L" debuted at No. 2 on the Billboard 200 last week.

After making inroads three years ago with a pair of mid-charting singles, Frankie Ballard scores his first No. 1 on Billboard's Nielsen BDS-based Country Airplay chart, as "Helluva Life" jumps 4-1. In his prior two chart visits, both in 2011, "Tell Me You Get Lonely" reached No. 33 and "A Buncha Girls" rose to No. 27. Ballard told Billboard last month that he knew that "Life," the lead single from his sophomore album, "Sunshine & Whiskey," "was going to touch people and speak to their journey, but I had no idea it would [get] the reaction that it has. This song speaks to things like hope, and getting up every day and putting one foot in front of the other no matter what kind of curve balls life throws you. People have really made the story their own."
