Musical.ly was a precursor to tik-tok ( block that from your children) but it was a lot of young children lip syncing and doing "dances" filled with satanic hand signs (sigils).This woman is right on, it doesn't matter that children are doing it because it's "cool", they are being used to put this out into the world by dark forces.i believe everyone strong enough in Christ to study the dark occults should, to know why they do this. Without that strong foundation, however, I would not recommend it.
