Gesaffelstein & The Weeknd’s “Lost In The Fire” did not officially launch until the sixth day of the January 6-12 tracking period.

Despite the late arrival, it amassed an impressive amount of pop radio airplay.

Credited with 637 tracking period spins, “Lost In The Fire” ranks as the Mediabase pop panel’s #45 song.

“Lost In The Fire” is one of two additions to this week’s Top 50. Sheck Wes’ “Mo Bamba,” the other, ascends two places to #50.

The rhythmic/urban crossover received 333 spins this week. The count actually trails last week’s mark by 12 plays.
