Tik Tok on the computer?

I started with Tik Tok the other day. But I'm more of a video game type and that's why I want to make Tik toks bon Minecraft, etc. But I don't understand how to upload Minecraft Tik toks on the PC with music? So far I have taken a very cumbersome way to still be able to insert music
