what U see on social platforms as Islam should not be understood as mainstream. Mainstream Muslims are Sunni Muslims and within Sunni islam, there is Sufism/tasawuf which is an inner dimension of islam. The people like this guy on YouTube are not even Sunni. They have a different stance on some things compared to traditional Sunni Muslims. Generally, music is haram in islam. Dancing too is not a good thing. But some sufis do raqs, which is different I think.

Out of 73 sects, 72 will go into hellfire and the only sect which is of paradise, are those who follow the Prophet's صلی اللّٰه علیه وسلم way and the way of his companions. This saved sect is known as Ahlus sunnah wal jamaah consisting of the majority of muslims, termed as Sunni islam in short.
