Set This Hidden iPhone Timer to Shut Your Music Off After You Fall Asleep

Rarely do I go to bed without something playing on my iPhone, usually a YouTube video. The problem is, I need to make sure the video is long enough for me to fall asleep to, but not so long it wakes up me down the line. Plus, I need to make sure autoplay is disabled, otherwise YouTube will be running through my recommended catalogue all night. At least, I had to worry about that, until I learned about my iPhone’s hidden sleep timer.If you’re like me, this problem probably bothers you
