Before distributing your music through A3Tunes, make sure your files meet professional standards. This includes high-quality WAV audio files (typically 16-bit, 44.1kHz), properly formatted track metadata (song title, artist name, genre, etc.), and professional cover artwork (3000×3000 pixels, JPG/PNG format). You should also prepare release details like the launch date, language, and contributing artists. A3Tunes provides a clear checklist and user-friendly interface to ensure everything is submitted correctly. Proper preparation ensures your music goes live smoothly and appears professionally across all platforms.
