Can you make use of these logs?

I have about 2000 EAC 1.0 beta 3 and 1.3 full disc rip logs and accompanying .cue files as well.
These logs have lots of information and I am wondering for those who have dealt with them what sort of information can/should be pulled out and into musicbrainz and how (all manual entry?).


Look up musicbrainz disc id and freedb id from EAC/XLD log might be helpful if you’re trying to match folders to specific releases

They can be used to generate discids (as briaguya said). I think you can also identify enhanced CDs with them. Really weird accuraterip results from early 2000s CDs are often evidence of CCCDs.
.cue files, if you have those, can be used to find ISRCs and barcodes.

I am not sure how I generate the Disc ID. I put a log into the search she linked and it gave me a bogus result. Turns out the disc wasn’t in the database at all, but it is concerning it gave me a random result.

The only part of the EAC log that needs to be pasted into that page is the TOC. A disc ID is then generated from that. Be aware that this is not perfect, but usually a good hit rate of getting the correct release.

How random is the result? A totally different artist?

Yes absolutely. Same number of tracks but completely different everything else.

It’s possible for two completely different releases to have the same discid, but that’s pretty rare. I’m guessing somebody made a mistake when submitting discIDs in the past.

As explained it can be used to identify your releases but to submit data from them you need to know the release source. Do you also have the covers?

Yes I have full scans of them, about 8k images to upload. I am more so looking to see if I should be pasting the TOC into a submission form or if there is a way to extract the ISRCs from a .cue without manual entry?

In this case you can add the TOC indeed, what is important is to trace back to the proper release. In other words, if you are unsure to which one it belongs, better not to add it.

For ISRC not aware of an automatic extract tool from cue but you have some scripts to help: or if the ISRCs match the digital versions you can use this


You can copy the entire cue file and paste it into magicisrc using jesus2099’s MASS ISRC script.


Thank you for gathering this data, and for thinking about how to contribute it to MusicBrainz.

I agree with the comment that scans of the physical releases are valuable to keep as part of the data set. It is very helpful to have the scans correlated with the log files and .cue files.

I see lots of people suggesting somewhat-automated, mostly manual tools for getting the data entered. That sounds to me like a good place to start. Once you have a workflow established, and you have a good idea which steps are repeatable and not very error-prone, you might start to wish for more automation. That may be where I can help. I am (and others here also are) good at writing simple Python programs to automate extraction of text from files, and calling MusicBrainz APIs. But trying the steps manually is an important preceding step, because that exploration tells you what the automation needs to do.

I would love to see these data added to MusicBrainz in a high-quality way, so I am enthusiastic for this effort to succeed.


Thanks for the support. My username on musicbrainz is also Soliloquy. I have just manually been adding a few images & releases over the last few days. Most of what I have seems to not be in the database, but that is O-K, just more work.
All of my folders also have a manually typed .info sheet which I have been using for tracklist adding. For example the last album I just added has this as it’s info sheet.
If there was a cat no or label that would be added to the info as well, but that is about it.

So if anything could be automated purely by reading those file(s), it’d be amazing.


Cool! What are these files named? What are the corresponding names of the files with scans? Is there a pattern to the filenames, such that if you see the name of one of these files, you can derive the names of the other files?


Yeah I have lots of patterns, ha.
Let me break down the filenaming starting with folder
folder is always
Artist - Release Title (Original Year) [Format] {Edition Information, Catalog Number Or Label}

So the end bracket has a lot of variability. If it is a CD-R that goes in. If it has a re-release year different than original that would be in.And then always the catalog number or if there is no catalog number then the label and if there is neither a Self-Released is included.

The files are all ## - Track Title (ft. Guest Artist, Guest Artist).flac
Seems like the best thing would be to look at the tags and properties of *.flac files within a selected folder and import data from that.It would make the tool more broadly useable, but a checksum’d .log could be used to verify the data comes from a disc as well to decrease false imports or user compilations.

What are the filename patterns of the log, cue, and info files, and of the scan files?

We were talking about log, cue, info, and scan files before. Adding FLAC files to the mix makes it more complicated. I guess it brings up the question of, what kind of data do you think these files could provide to MusicBrainz?

Where there are existing Release entries, and we can establish that a particular set of log, cue, info and scan files definitely correspond to an existing Release entry, then we could perhaps add CD TOC, ISRC, and cover art to the Release entry.

Where we can establish that no existing Release entry corresponds to a particular set of log, cue, info and scan files, then the obvious contribution is to add the Release entry. But in my experience, the time-consuming part of adding a Release entry is adding the Artist entries needed to make the Release entry — the album artists, the composers, and the performers.

Posting a file listing all the file names with all their directory paths would be helpful.

And as I said before, the first step in automation is to do the task manually. Take a couple of the entries as pathfinders. Manually look for existing Release entries. Write down what steps you take to search. Write down the criteria you use to determine that Release entries do or do not match. Is it possible to do the task manually? If not, then automation is likely fruitless. If so, then those notes provide the starting point for the automation.
