Kacey Musgraves' "Rainbow," a sweet highlight of the Grammy telecast and the new single from her Album of the Year-snagging Golden Hour (Mercury Nashville), is off to a strong start at Country radio. The track is #3 Most Added at the format—which has taken mondo heat of late for not playing females—with 37 adds and 53 total stations thus far. It's also well underway at AC.

As the Jason Owen-repped Musgraves, who also took Country Album, Country Song and Country Solo Performance, takes off among consumers (she's #1 at iTunes and trending Top 10 at Apple Music, where hip-hop and R&B tend to rule), how many more programmers—and formats—will come to the table?
