About
Hi, I'm the person behind Metadata.
This service started as a tool I built for my own classical and jazz library. Mainstream tagging tools fall short on what these genres actually need — composer / work / movement structure, catalogue refs, role-aware artist credits — so I wrote my own pipeline that does what I wanted. Friends asked if they could hand me their libraries; that's how this became a service.
It's a one-person operation. There's no team, no support queue, no ticket system — when you email or message, you reach me directly. That has obvious downsides (slower turnaround than a fully-staffed service) and obvious upsides (every job gets the same person who built the pipeline; quality stays consistent).
On MusicBrainz
MusicBrainz user since 2018, with 415+ releases added — profile at musicbrainz.org/user/nadl40.
The pipeline runs against a self-hosted MB mirror, and missing data ends up back in public MB as part of the work (see the home page for how the contribution loop fits into pricing).
Why classical and jazz only
Both genres have rich, structured metadata that mainstream taggers ignore — composer / work / movement / catalogue / role-aware artists for classical; per-track personnel with instrument abbreviations for jazz. Both have collectors who care deeply about getting it right. Both align with what the pipeline already handles well.
Pop, rock, electronic, and ambient tend to need different metadata models — and honestly, I'd rather work on the music I actually listen to.
Hobby scale, real commitment
This is a side project. Capacity is around 75-100 CDs a week — see How it works for the workflow. I take it seriously within the time I can give it; if that's slower than what a larger operation could promise, the trade-off is that you're working with the person who actually built and runs the pipeline.
