The Growlers' song "Let It Be Known" is about a person who is dealing with someone else's bottled up emotions and negative behavior. The speaker expresses their frustration with constantly trying to guess what the other person is feeling and walking on eggshells around them. They want the other person to communicate their feelings instead of bringing past issues into the present. The lyrics suggest that the speaker is tired of the negativity and wants the other person to let them know what is going on. They refuse to take the blame for the other person's emotions and don't want to be affected by their negativity anymore. The speaker also questions if there is someone else influencing the other person's anger and if they have done something to feel betrayed. The song portrays the speaker's plea for honesty and openness in their relationship. They want to understand if the other person has changed or if something else is causing their negative behavior. Ultimately, the speaker wants to prevent the relationship from sinking and to have clarity and peace with the other person.
