Over on the Digital Songs chart, Pharrell's "Happy" spends another week at No. 1, selling 413,000 downloads (up 3%). A week ago, it sold 402,000. "Happy" is the first song to earn two straight weeks of more than 400,000 in sales since another Pharrell-related song: "Blurred Lines." The Robin Thicke-led track (which featured T.I. and Pharrell) sold in excess of 400,000 in the three consecutive weeksending June 23, 2013.

"Happy" has a gain thanks to its growing popularity on the radio and because of its performance on the Academy Awards on March 2. On the Mainstream Top 40 airplay chart (known as Pop Songs on Billboard.com), "Happy" rises 10-4.
