Because of some unfortunate circumstances I noticed I irrevertibly mixed up my sorted and retagged mp3s with an old backup. That means now I have files that are basically duplicates except for the id3 tags and paths. FSlint does a nice job of finding real duplicates, but is there any free tool to detect duplicate mp3s that differ in their ID3s? My preference is a linux tool, but windows would be acceptable, too.

I guess you know about Picard, which can take acoustic fingerprints and uses them to find out the appropriate tags? Maybe you can retag the MP3s and then sort out the duplicates. – slhck Jun 25 '11 at 20:44
@slhck thanks for mentioning it, yes picard is what I'll be using (again) if no automated solution shows up – Tobias Kienzler Jun 25 '11 at 20:47
You can try using this Windows tool from codeproject which is available both as source code and executable. Here's a blog post about how it works internally. Since I haven't used it myself and don't know how it handles extremely large collections, posting only a comment. – Daniel Beck Jun 25 '11 at 20:49

EasyTAG can do this all and more easily. Most importantly for your purposes, it allows you to define and use a naming scheme based on the ID3 tags.

Edit: After rereading the question, this isn't exactly what you wanted. However, after renaming the files, you can use FSlint to delete the duplicates.

easytag is a good tool, I'm basically doing what you suggest with picard now - first retagging (again...) and then fslint. – Tobias Kienzler Jun 25 '11 at 22:11
in addition to easyTAG and picard I'm now also using DupeGuru for some good (almost)dupe search – Tobias Kienzler Aug 26 '11 at 20:20

DupeGuru does a nice job comparing tags or also only the audio content.


DuMP3 claims even more features but I didn't spend enough effort to get it running (32 bit SWT on 64 bit linux...)

DupeMusicMatch might also help, but I didn't try that yet.
