How to stream music?

Question

Video broadcast

Hello, dear friends, I have a question:
How can I still stream music to twitch.
That is, not to stream yourself, but to play music on the channel 24/7 with a beautiful visualizer, for example, like Monstercat, or the same NCS.
There are those who fumbles and can explain normally?
I turned to Google, but I did not find the answer.
