What Is Music Metadata
Music metadata is the structured information attached to a recording or release that describes its content, ownership and technical characteristics. It includes everything from the song title and artist name to ISRC codes, UPC barcodes and embedded audio tags.
Every time a track is played on a streaming platform, metadata determines how royalties are calculated, how the track appears in search results and how it is categorized in databases worldwide.
Why Metadata Matters
Accurate metadata is the foundation of the modern music industry. It directly impacts:
- Royalty Collection — Incorrect metadata means unmatched recordings and lost revenue.
- Discoverability — Proper tags help listeners find your music through search and recommendations.
- Credit & Attribution — Contributors, producers and songwriters receive proper credit.
- Distribution — Platforms reject releases with incomplete or inaccurate metadata.
Core Metadata Fields
Every release requires these essential fields:
- Track Title — Official name of the recording.
- Artist Name — Primary artist or band name as it appears on the platform.
- Featured Artists — Any collaborating or featured artists.
- Album Title — Parent album or EP name.
- Genre — Primary and secondary genre classification.
- Release Date — Official global release date.
- ISRC — Unique identifier for each recording.
- UPC/EAN — Unique identifier for the release.
- Track Number — Position in the tracklist.
- Disc Number — For multi-disc releases.
- Explicit Flag — Whether the content contains explicit material.
- Language — Language of the lyrics.
Technical Metadata
Beyond content description, technical metadata describes the audio file itself:
- Sample Rate — 44,100 Hz is the industry standard.
- Bit Depth — 16-bit for standard, 24-bit for hi-res.
- Format — WAV, FLAC, ALAC, MP3, AAC, OGG.
- Bitrate — 320 kbps for MP3, lossless for WAV/FLAC.
- Channels — Stereo is standard, mono for specific use cases.
- Duration — Track length in minutes and seconds.
Best Practices
- Use consistent artist names across all releases.
- Never use special characters in titles unless part of the official name.
- Verify ISRC codes before submission.
- Include all contributors and their roles.
- Use proper capitalization — avoid ALL CAPS or all lowercase.
- Keep metadata consistent across all platforms.
Common Mistakes
