 Thankfully, the Redditor came up with a clever hack to make sure his neighbor can control the volume of his music with just a simple text message. By adding a shortcut to his phone, he made sure that if he receives a message saying volume down from that neighbor, the volume drops from 100% down to 70%. Even at 70%, the Redditor can still enjoy his shower concerts, but the music is low enough to ensure there's no sound leakage into his neighbor's home.
