Why Mamamoo didnt had a big jump in sales like most groups had in 2022?

Their fandom is not as big?

Well, Mamamoo isn't as big as Red Velvet, and their last comeback wasn't that good (My opinion).

Because their fandom is eco friendly and they do not wanna burden environment

Because cow didn't say moo

This.

We're just trying to do our part as a fandom to help create a greener Earth.

You all can have your albums with 20 different versions

Their last album make 135k aprox. Very similar to their previous sales. In comparison, RV make a big jump with Feel my Rythm (aprox 700K)from their previous album sales (400k aprox) So, what happen?

Huh, weird indeed.

I thought that every K-pop boy and girl group incl. Mamamoo increased their album sales 3-5 times from 2020 onward.

But I checked and you're right: no major jump for Mamamoo the past years. Odd.

Unless the jump from ca. 70k in 2019 to 180k in 2020 should be regarded as their major jump?

Seeing how their EP album sales hovered around 60-70k steady for 3-4 years in 2016-2019 and then made the abrupt jump like all K-pop groups experienced from 2020 onwards.

So, what happen?

The company limits production, the fandom has been struggling for years to get restocking, some albums have become very difficult to find.

I think, have they continued having hits like hip they would have bigger album sales, but mamamoo hasn't had hip level of success internally in years.
