She should definitely end the No. 1s residency in September.
It's not doing so well, right?
Plus she needs to take time to focus on new material.
I think after that the next residency should be a short one (not a ton of dates) with just album tracks and rarely performed songs at an intimate venue.
Personally, I think it would be amazing if she did a couple dates for each album.
Like the first few could be for the 'Mariah Carey' album, the next few for the 'Emotions' album, etc. Maybe some could have a few more dates than others like Butterfly & Daydream for example.
