Repeat a YouTube video
When you've got an earworm from a YouTube track, you just want to hear it again and again.
Sure, you can go in and press repeat or replay every time the song finishes, but here's an even easier way to do it.
Head to the URL bar, and after the word "YouTube" and before ".com" — just type in "repeat". Hit "enter" and you suddenly have as many irritating, endlessly looping songs as you could ever want.
