Fight fire with fire
I recommend playing suitable music that will be heard and put them off their stroke.

1: Everybody hurts, REM.
2: Theme from Postman Pat.
3: The frog Chorus, Paul McCartney.
4. Anything from the Magic Flute, by that Mozart geezer.

Too much beat
The music must not have a "pumping" beat.

Good,
but it builds up to a climax.

which rather defeats the object. Unless you play it twice, or stop it just before it gets interesting.
