I understand that MusicBrainz is only for released music recordings. Unreleased and bootleg albums reiterates that. But I have this private, unreleased stuff which I would like to have MusicBrainz help me with. Is there a way?
One example is my custom retracking of a Release. A DVD concert recording was released, and I added it to MusicBrainz. But the people who mastered it, bless their hearts, put the DVD chapter boundaries at curious locations, often unrelated to the movement divisions of the work. So I fired up ffmpeg and split the unitary soundtrack of the whole DVD into my own per-movement audio files. I would love to re-use the Release-level titles, artists, and relationships. I can re-use most of the Track-level artists and relationships, but I tweak the Track Titles and times.
What I want is to be able to tell Picard, "tag my per-movement audio files by taking my list of Tracks and Relationships, and falling back to Release cbc2c for everything else.
A second example is privately-shared audio files. An composer gave me some personal recordings of performances of his works, to introduce his work to me. I can be sure that there is an Artist entry and Work entries. But I don’t think these particular recordings are public enough to justify adding them to MusicBrainz.
What I want is to be able to tell Picard, “tag my private audio files as non-album tracks, by using my per-track data and Relationships, and falling back to Artist and Work entries from MusicBrainz”.
A third example is an Artist’s promotional recordings. I downloaded them as audio files from the Samples section of the website. The Artist didn’t clearly say, please download these and keep them, but also didn’t do anything to prevent that. Since then, the Artist remodeled their website, and the Samples section is gone.
What I want is to be able to tell Picard, “tag my promotional audio files as non-album tracks, by using my per-track data and Relationships, and falling back to Artist and Work entries from MusicBrainz”.
Here I may actually have a leg to stand on. Can I justify adding these audio files to MusicBrainz, because the Artist did at one time present them in a way that was almost publicly releasing them?
If I could author some metadata into an XML file, which could reference MusicBrainz via MBIDs; and if Picard could read this XML file, then that might give me what I want.
If I could make entries in to MusicBrainz but mark them “private”, that might give me what I want. It would keep private data out of MusicBrainz’s public database, but would still increase MusicBrainz’s size and demands.
If I could make a private MusicBrainz server instance, which stored my private entries but passed on all unresolved MBIDs to the main MusicBrainz, that might give me what I want.
Any idea how to accomplish this? Are there feature requests already written for this, for I should be voting?
