A Youtube tip for your Autism/ADHD/Musical Hyper fixation?

Find the Youtube video you want, and type in "repeater" after the word youtube. It will replay the same video/song over and over, forever.

Hard to put an example, but:

If youtube vids have youtube dot com, you would type in youtuberepeater dot com. (with the rest if the link)

I tried to link an example but it is "not supported".
