Tagging fails: ValueError: math domain error

[onny]

Hey, I have another corrupt file and maybe we can catch the exception it throws: https://nextcloud.project-insanity.org/s/XaexSNjZZkHjANT

r128gain -c1 -s 04-There\'s\ No\ Other\ Way.mp3 
Analyzing loudness of file '04-There's No Other Way.mp3'...

ValueError: math domain error

Unfortunately the tagging of the album fails with this one corrupt file.

Best regards, Jonas

Thanks for the report and file.

That file seems invalid, but it is actually successfully decoded by FFmpeg, and contains only a few sample of digital silence, which triggers a bug in my code.

It should be fixed now.
