For MP3 files, synced lyrics are embedded in the SYLT tag. Unfortunately, not many music players support this across platforms.
That could be the case. I used ffprobe to see the tags and figured it would just display the tags it sees. I’ll look more into it.
We’re just poking for a bit of fun. The Free and Open Source rabbit hole goes very deep. For example, Intel and AMD processors have code on them that isn’t free meaning the purists will not use them unmodified.
Everyone has a threshold where privacy and freedom interfere with convenience, just stick with the level you’re comfortable with.
