I created a one-hour long silent MP3 and named it similarly and added it to my phone. I've sent it to a friend who uses it as well.

I have a script (simple ffmpeg wrapper) to generate silent mp3 files:

I'm not quite sure what I needed that for anymore, but I find it interesting that there are such weird use cases for this.

Call it Subliminal productivity silence and you can make a fortune.
