Loud music

Every morning at 7:00-7:30 AM downstairs is playing loud music and continues on throughout the whole day. I’m hearing the bass radiate and coming from my bedroom. I just want to sleep in for once. I’ve gone downstairs to try to figure out which unit the music is coming from but I can’t pin point the exact location. I can literally hear the music/base in the halls. Should I just leave a note downstairs in the hallway?
