Looking at some of those callout reports over time, I've noticed that a majority of the songs that stayed perched high on the positive feedback list (for weeks and months before really taking off) ended up going #1 on the Pop charts there (GYHAB, Lights, Can't Hold Us, One More Night, Wide Awake, etc.).
Looks like Same Love and Cups have been perched really high since April/May. Maybe they'll follow the same footsteps?
