I have got from a neighbor of me a crashed disk with many ten thousands of mp3 files.
After running a data recovery program, I got thousands of records with only a general filename (FILE00000-FILE35000) without album, title, artist.
Searching for programs that can identify this files, I found Picard.
And yes, with this program I could recover many of these files.
But also many of them not.
What can be the reasons?
A reason, I though of, is that the file is not available in the MusicBrainz database.
For instance, Mozart, Quintet in G minor, K516.
I found also other tag programs with a connect to Discogs, but not suitable for my files was my conclusion.
Still, when searching in Discogs database, I find many hits of these Mozart mp3 files.
And WikiPedia shows as info:
Discogs : 151,200,000 tracks
MusicBrainz : ~28,608,635 tracks
So I want to verify now if my conclusion is right, that not all (my) mp3 files will be found in the MusicBrainz database and therefore Picard will not find info about these mp3 files.
Other programs I have used with no results are MP3tag, Tagscan, MusicBee, Kid3.
If someone knows a good alternative, I will be very greatfull to get info about it.
Finally, I think my English is not perfect, I have learned English at a Dutch school in 1959-1965, my apology for this.
