kids pick up on all the “small” stuff going on in the home. they watch and hear how you speak with your spouse. they see and hear if you are happy to come home after a hard days work and don’t run out the door for all the outside stuff. you do not need the music. it will not bring you closer to how you feel with your shared quality time with your spouse. do you enjoy going for a stroll together, do you enjoy playing a game shabbos afternoon together? that they will pick up on.
