How do I add a song to autoplay on a loop to my profile?

you have it in layouts you can search for it or click song in the layouts section, just copy and paste it like you would a layout 

gl! ^•^

HEYY!!! so I know this is a few days late but here's how I got mine to work.

STEP #1: You first need to copy the following text into any one of your text boxes on your profile

<iframe width="0" height="0" src="https://www.youtube.com/embed/LINK HERE//?&;amp;;autoplay=1&;loop=1&;controls=1" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" loading="lazy">

</iframe>

STEP # 2: Find a video from YouTube that has the song you want to play and look at the link.

- For example, the link may look like: https://www.youtube.com/watch?v=heyhtaxoGI0

- In the link, I've highlighted the last couple of characters

STEP #3: In the section of code that I've labeled "LINK HERE" type the characters that follow the = in ur link. In this example, they are heyhtaxoGI0

The Final Thing should  look like

<iframe width="0" height="0" src="https://www.youtube.com/embed/heyhtaxoGI0//?&;amp;;autoplay=1&;loop=1&;controls=1" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" loading="lazy">

</iframe>

*If you have any questions feel free to ask further ! :3
