I had a whole lot of songs I downloaded online and not always directly from the album that has everything organized; album name, artist, genre, etc.
This software scans your music library and does all that for you and adds album art.
I would say it’s 98.5% accurate. Only a few songs it renamed to the wrong thing. So look out for that. But it ask for your confirmation before it edits the song info.
It does it in batch by the way
For the longest time I’d use MP3tag in Windows, which is still a great tool, runs great in Wine, and it can do some of the same things like look up artwork and in particular rename files based on tags.
But less than a month ago I downloaded Picard and have been getting into using it, and the workflow is quite strange. But it works. And I can recommend it.
