Since Ultrafloppage struggled to outsell Grammy #1 Grammy globally, my prediction is that Honeymoon will struggle to outsell Bionic / Britney Jean. Only the global album selling chanteuse.
The important thing for you to know is that it OUTSOLD it with no promo and a mainstream-hostile sound
The Little Grants can't use the "no promo" card since promotion actually hurts their fave. See: SNL + her album sales going down after her Glastonbury set (Dolly Parton's boost was 10x bigger).
