I love Janet alot but compared to her in 2010 to today in 2023 I think she needs to rest.
While I don't care how she dances seeing her is amazing, for the majority and for the sake of new fans it's underwhelming seeing the music videos at such a a speed to go to one of her concerts live with her dancing at the speed of a .75 YouTube video. So not only is she not making much content she's also reusing (Very good) content that doesn't attract new fans.
Personally for the best of both worlds I feel like she should drop most of her old music and focus on a few new tunes that she can better express without having to cut corners.
