Mp3tag – Universal Tag Editor

Original Article ↗ Hacker News Discussion ↗

Meticulous tagging of local music libraries remains a point of pride and practicality for many, and Mp3tag — a two‑decades‑old tag editor — is still a central tool in that workflow. Commenters describe elaborate setups for ripping CDs to lossless formats, auto‑fetching metadata via tools like MusicBrainz Picard or beets, normalizing volume, and backing up archives to hard drives and optical media, driven partly by distrust of streaming services’ longevity and recommendation algorithms. The thread also surveys a wide ecosystem of alternatives and complements across platforms, highlighting both the power of specialized tag editors and the persistent messiness of metadata standards for genres, ratings, and multi‑artist releases.

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.
