Ed Sheeran looks to have a bona fide pop hit on his hands.

For the second consecutive week, his “Sing” reigns as Top 40 radio’s most-added song.

Distanced sufficiently from the field, the Pharrell-produced track and lead “x” single scored an impressive 72 adds this week, according to Mediabase’s Tuesday report. Lady Gaga’s “GUY,” the next best performer, followed with 39 adds.

5 Seconds of Summer’s breakthrough “She Looks So Perfect” followed with 26 adds, while DJ Snake & Lil Jon’s “Turn Down for What” (24) and Nico & Vinz’ exploding “Am I Wrong” (24) closed out the top five.

Just outside of the Top 5 was KONGOS’ alternative smash “Come With Me Now.” Sixth for the week, the band’s crossover attempt scored adds from a solid 23 Top 40 stations.

19 added Iggy Azalea’s pop breakthrough “Fancy (featuring Charli XCX),” while 18 latched onto Katy Perry’s new single “Birthday.” “Rude,” from buzzworthy Canadian act MAGIC!, landed in ninth with 16 adds, while My Crazy Girlfriend’s “Crazy Stupid Love” remains in the top 10 thanks to its 14 adds.

Notables outside the top ten:

*Several of last week’s impacting tracks, including Afrojack’s “Ten Feet Tall (featuring Wrabel)” (12 adds), Cher Lloyd’s “Sirens” (10 adds), HAIM’s “Forever” (9 adds) and AJR’s “I’m Ready” (7 adds) remained in the mix.

*Oh Honey’s “Be Okay,” which received exposure on “Glee” last month, picked up 11 of the format’s stations.

*Alicia Keys’ “It’s On Again (featuring Kendrick Lamar),” which appears on the soundtrack to “The Amazing Spider-Man 2,” scored nine weekly adds.
