I want an app that plays music that we know the person next to us will hate

Knowing music preferences is hard - but the opposite... that is easy!<br><br>I want an app that plays music that we know the person next to us will hate. For example: <br>- My partner, who has a very eclectic taste in music, will run out of the room whenever we play reggaeton - so if he opens up the app, he will hear reggaeton.<br>- I, on the other hand, hate bagpipes - so if I open the app, it will play bagpipes. And we can watch each other (living our lives) and hate this music together in peace!<br><br>Is there such an app? Should there be one?
