The song is dropping because of other songs rising faster. i just checked the mediabase pdf archive and KDL has decreased spins on many stations from 2 to 10 only because some other songs like Drake's SFTB raised 50 spins on the same station. Thats why it shows increases and decreases. At this point promo could make the difference but i guess they'e gonna save that for the album release just like they did for here i am. It is also raising in many stations that's why we haven't seen a big drop.
