Media tags not working for FLAC files

[basscheffers]

Thanks for adding media tags support! 👍

But unfortunately, they do not seem to work for FLAC files, even though jsmediatags says it supports it.

@basscheffers can't reproduce. Could you link the flac file you've tested?

[basscheffers]

Mystery solved! It turns out the ripper I used (dbPowerAmp) creates tags with keys like "Title". If I open the same file in a tag editor, or a player like Audirvana, it works just fine. But (presumably) jsmediatags is case sensitive to keys and doesn't read it.

In the screenshot, the bottom file was re-saved by a tag editor, and it works. In the top file I manually changed the "Title" key to "TITLE" in the hex editor and guess what? That was enough to make it work in Web Minidisc when I chose "Title" for track name.

So yeah, sounds like jsmediatags is the most likely culprit here? If they just make theirs case insensitive, it would fix it in Web Minidisc too.

Also attached is a small FLAC with the same issue.

Thanks!
Bas.

@basscheffers Thanks for taking the time to look into this.
We could reach out to the jsmediatags maintainers by opening an issue and providing the steps to reproduce.
The fix is potentially easy, so we could also offer some help in crafting a PR.
Is this something you've time to do? Or should I take care when I'll have some free time?

Ref: aadsm/jsmediatags#90
Seems folks already encountered the issue. Suggested fix was to use https://github.com/Borewit/music-metadata instead of jsmediatags, not sure how much effort that would entail...

I will try to take a stab at it this weekend. The current lib uses onSuccess: handlers and music-metadata uses async call in the example, so some tweaking needs to be done. Also, I have no prior knowledge of node/typescript.
