Well, here is my theory: If that photo on instagram with the stripes mean a calendar and on the 13th there is an LPU logo, then I think it means the new LPU app will launch that time probably (Feb 13th) with more details a about the new single (artwork, tracklist, radio premiere time, etc). Considering that LP always had a radio world premiere for their lead singles, I think it is going to be heard first on radio and the 17th of February is the release date for the physical or digital copy of the single since Warner posted about it, not a radio station. If that is correct, then we will hear "Heavy" before the 17th of February which is most likely around valentine's day and it will air on radio... probably on Beats 1. If that pattern countinues with the clip release dates (monday-wednesday-friday) then we will get the final one on the 20th of Feb and if that "One month" prediction is correct about the URL, then the album will drop on the 20th of March which is also a monday.
(Lol, so many "if"s )
