Possible, I liked the choreography in AF, but agree that it is not easy for ordinary folks, compared to their older hits which had simpler yet specfic movements for anyone to try.
Still that alone can't be the reason.
I am not sure about the decline - but for Scientist, didn't they still reach Top 10?
And whatever they were thinking about Cry For Me. A bad strategy for MAMA, indeed made the ONCEs Cry For Them.
Still I don't see why a GG which still hits Top 10 is written off so easily just by 1 aberration and 1 underperformer. Hardly enough for a pattern.
If this comeback doesn't make Top 10, and then another.. Then 3 consecutive underperforming ones can constitute a pattern of decline.
