When I go on youtube I either go for entertainment or information, for entertainment I watch BTS (and other groups like Seventeen, NCT 127, Got7, etc. dance practice videos, or music videos and a lot of those groups funniest moments, live performances and stuff. Also korean dramas.
For info, I watch videos from our ministry, and also John Taylor Gatto's speeches, things like that. Also language lessons, I'm trying to learn Korean.
