how do i make music on my profile repeat/loop/play forever?

i've been trying to find the answer for some time now, but no one seems to know.

every time i refresh my profile the song plays one single time and then stops until you manually make it repeat again. is there any way to make it automatically repeat?

here's the code im currently using:

<iframe width="300" height="50" src="https://www.youtube.com/embed/URL//?&;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>

i've tried changing the numbers for "autoplay" and "loop" to something higher than 1, but that didn't seem to do anything...

help plz >_<*
