Thank you so much for your kindness and help. I ask if background or incidental music is permitted during The Three Weeks e.g. programs with incidental music via radio, internet, or other etc.
I listen and watch programs and other media not doing so to listen to the background music but often it is there in the background within those programs and the like.
I always want to do the right thing.
A person that is in a place that has music playing does not have to leave, and doesn’t have to be concerned that he is hearing music during the three weeks. Examples of this are; when on a bus, in an office, or a store that has back round music, the music of a ringing phone. The reason for this is because the person does not have intention to enjoy the music, rather he can’t help but to hear it, therefore it is permitted.
