I say her label PAYS distribution centers and other ways of selling albums WW to keep hush hush and release it PHYSICALLY AND DIGITALLY on the same day to get that 2 mil first week
Edit: Actually, on second thought, RELEASE the tracklist without lengths and/or producer names online. The next day, RELEASE the album artwork. Day after, make the album available for pre order WITHOUT a release date. GET that 1.5 mil pre order and RELEASE it randomly yes adele
