Mp3tag – Universal Tag Editor

Original Article ↗ Hacker News Discussion ↗

Longevity and Role of Mp3tag

  • Seen as a “classic” tool dating back to early 2000s, still actively maintained and highly trusted.
  • Many users still rely on it as their primary batch tag editor; praised for speed, robustness, and thoughtful design.
  • Some use it in conjunction with database-based taggers (e.g., MusicBrainz Picard) for final cleanup and custom tweaks.

Workflows for Local Music Libraries

  • Common pipeline: buy used CDs → rip to FLAC (often with EAC or CueRipper) → autotag with beets/Picard → transcode to MP3/AAC/Opus for devices.
  • Some maintain lossless master archives (FLAC) and convert on demand; MP3 remains popular for maximum device compatibility (cars, old radios, etc.).
  • Users differ on preferred bitrates: 192kbps vs V0 vs 320kbps, with arguments over space vs quality.

Streaming vs Local Collections

  • Many remain wary of relying on Spotify and similar services due to disappearing content, price changes, or algorithmic repetition.
  • Self-hosted solutions (Navidrome, Plexamp) and local players (foobar2000, cmus, MediaMonkey, Strawberry, etc.) are preferred by some for control and gapless playback.

Metadata & Tagging Challenges

  • Genre and classical metadata are described as a “mess”; attempts to use nonstandard fields (e.g., Grouping) often break across players.
  • ID3 has odd frames (e.g., Popularimeter for ratings/play count); some migrate iTunes metadata into these.
  • Volume normalization splits users between ReplayGain tags and mp3gain-level modifications, depending on player support.
  • Desire for impeccable, consistent tagging is common; some consider it a hobby or “badge of honor.”

Tools, Platforms, and Alternatives

  • Alternatives mentioned: EasyTAG, Kid3, Puddletag, Meta, Yate, Foobar2000 tagger, beets, QuodLibet/ExFalso, AtomicParsley, mutagen, CLI tools like id3v2/id3tag.
  • Mp3tag is closed source, Windows-native, but works well via Wine; macOS has a paid native version that users find performant.
  • Some lament the lack of a unified, OS-level metadata system across file types.

Archival, Privacy, and Automation

  • Archival strategies include Blu-ray plus HDDs as part of a 3–2–1 backup, partly for ransomware resilience.
  • Concern that online metadata services log lookups; some prefer minimizing such calls.
  • Scripts and automation (PowerShell, Python, beets actions, Mp3tag actions) are heavily used; LLM-based tagging is floated but met with unease.
