how to make a youtube music player ACTUALLY loop

youtubes weird, the only way to make the "loop=1" thing work is to put it in a playlist, but you dont need to do that, just add "playlist=VIDEOID" to the embed code (replacing it with video id of course) to make it actually loop, so it looks like this:

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

and once again, replace VIDEOID with the videos actual id
