Good metadata is the foundation of an organized music library. Properly tagged files display correctly in any player, sort properly, and are easy to find.
Why Tagging Matters
- Correct display – Artist, album, and track names appear properly
- Proper sorting – Albums stay together, tracks in order
- Search and filtering – Find music by artist, genre, year
- Album art – Cover images display in your player
- Portability – Tags travel with files to any device
Essential Tags
| Tag | Purpose | Example |
|---|---|---|
| Title | Track name | Bohemian Rhapsody |
| Artist | Performer | Queen |
| Album | Album name | A Night at the Opera |
| Album Artist | Primary artist (for sorting) | Queen |
| Track Number | Position on album | 11 |
| Disc Number | For multi-disc albums | 1 |
| Year | Release year | 1975 |
| Genre | Music category | Rock |
Album Artist is Crucial
The Album Artist tag keeps albums together when tracks have different artists (like collaborations or compilations). Without it, your library becomes fragmented.

beets (Command-line)
For power users who want automation. Can auto-tag and organize your entire library based on rules.
Tagging Best Practices
1. Be Consistent
Pick a style and stick with it:
- Artist names: "The Beatles" not "Beatles, The"
- Features: "Artist (feat. Guest)" or "Artist feat. Guest" – pick one
- Capitalization: Title Case or Sentence case – be consistent
2. Use Album Artist for Compilations
For compilations and soundtracks:
- Artist: The actual performer of each track
- Album Artist: "Various Artists" or the compilation name
This keeps the album together while showing the correct artist for each track.
3. Handle "The" Correctly
Keep "The" at the beginning: "The Beatles" not "Beatles, The". Most players handle sorting correctly with "The" included.
4. Track Numbers
Use proper numeric values (1, 2, 3) not strings ("01", "02"). For display purposes, most players add leading zeros automatically.
For multi-disc albums, use the Disc Number tag rather than putting disc info in the track number.
5. Year vs Date
The "Year" tag should be the original release year, not remaster or reissue dates. This helps with chronological browsing.
Album Art Guidelines
Resolution
- Minimum: 500x500 pixels
- Recommended: 1000x1000 or higher
- Maximum useful: Around 1500x1500 (larger is unnecessary)
Format
- JPEG for photographs
- PNG for artwork with transparency or sharp edges
- Keep file size reasonable (under 1MB typically)
Embedding vs External
Embedded art (stored inside the audio file) is more portable—the art travels with the file. External art (folder.jpg) is easier to change but may not display everywhere.
Recommendation: Embed art into files, and optionally keep a folder.jpg as backup.
Common Tagging Mistakes
- Missing Album Artist – Breaks compilations and featured tracks
- Inconsistent artist names – Same artist appears multiple times
- Genre abuse – Too specific ("Progressive Symphonic Power Metal")
- Missing track numbers – Album plays in wrong order
- Wrong year – Remaster year instead of original release
- Low-res album art – Looks bad on modern displays
