The NAD edition of Northern Star isn’t "wildly available". It isn’t in stock on Amazon or HMV anymore, although it wasn’t supposed to be as limited as the RSD edition. As for the Reason vinyl, if it "flopped", then AGLM flopped too. As for the self-titled album, excluding its first week, it achieved an additional 2,500 sales in the month that followed its release, taking its total to 9,700 as of November 2020. Taking into account its streaming performance since then, I wouldn’t be surprised if its UK sales have now surpassed all her albums since Beautiful Intentions, which is no mean feat.
