Late last year, Camila Cabello’s “Havana (featuring Young Thug)” reached #1 at pop and rhythmic radio.

This week, it will almost certainly ascend to #1 on the Mediabase hot adult contemporary chart.

“Havana” received 3,833 Hot AC spins during the first four days of the February 18-24 tracking period. Up 2.5% from the count at this point last week, the tally slots “Havana” at #1 on Mediabase’s building Hot AC chart.

While “Havana” only maintains an eighteen-spin lead over Ed Sheeran’s building #2 “Perfect,” it possesses a considerable momentum advantage. “Havana,” as noted, is up 2.5% week-over-week. “Perfect” is down 1.8%.

Assuming the songs remain on those rough trajectories, “Havana” should secure its lead as the tracking week comes to a close.

“Havana” will be Cabello’s first career #1 (including all solo, collaborative and Fifth Harmony songs) at the hot adult contemporary format.
