These guys are so front loaded as hell. Their sales nose dive 10 minutes after release.
Their singles are typically front loaded. Their albums have sold consistently post first week. 2M for UAN/TMH, 1.5M for MM and 1 million for FOUR (which didn't have any hits).
Is that from the US? Because if so, the instant grat of Drag Me Down that comes with the pre-order should be selling 5 times more than Hotline Bling, which is not the case.
I imagine most fans pre-ordering the album on iTunes already own DMD, so it wouldn't be purchased again. Plus they must get plenty of physical pre-orders.
