To submit a song to a radio station, you typically need to create a professional-quality recording of your song, preferably in a standard format like MP3. Research the radio station's submission guidelines, which are often available on their website, and follow the instructions provided. This usually involves filling out an online form or sending an email with your song, artist information, and any relevant details. Be sure to include a brief but compelling artist bio and a catchy one-sheet highlighting the key aspects of your song.
