Since we rarely get this type of data it is hard to tell if this is good or not & how much it matters.
If you need something to compare, The 20/20 Experience holds the current record for digital pre-orders with over 140k copies sold through pre-orders in just 4 weeks.
Not to mention you get a brand new song with Bangerz while you get a song that has already sold +1m with PRISM
People ignoring the details to justify their shade. I'm more interested in ARTPOP's preorder sales. If around 25K sounds right, she better hope her singles pull in more of the GP.
