I have the power to ruin your journey by public transport
I have a mobile 'phone with a little speaker in the back, which plays music.

Pray to your god that I am not an arrogant, stabby teenager.

You could make one.
It would be illegal.

You could make enough interference with one of these to make them turn the phone off.

I don't think this would interfere with the playback of mp3s through shitty, shitty speakers.
Sadly.

I believe
elsewhere on b3ta, there is a post about an obese man subverting this unfortunate habit of be-acned youths by dancing enthusiastically to the noise of their pop-gusting sound-spouts. Perturbed, they desist.

I personally prefer preempting them by playing Vivaldi; it would be Wagner, but my beefed-up android doesn't really have the bass for it.
