My thing with Glory and Lemonade is this:
Beyonce got very experimental (for a pop artist) with Lemonade. It's super interesting, and a nice change of pace. However, because it's so experimental, the songs don't have the same replay value (except maybe Formation) that her songs usually do.
With Glory, Britney got a little more experimental, but not to the point that you lose the replay value. It's different for HER, but not entirely removed from the current landscape of popular music. It has replay value. It's catchy.
Whereas I personally found most of Lemonade to be like an explosion of emotion over very interesting and different production, Glory seems more calculated. It seems much less like "I wrote this song because I'm angry and I went in and recorded the raw lyrics I wrote" and more "I am inspired by this emotion but let's turn it into a catchy, dark pop track that's more digestible for the masses". If any of that makes sense.
