loudgain refuses to write tags to this MP3 file
Actually, I have a few albums for which loudgain successfully calculates the gain, but then it just doesn't write the MP3 tags to the file despite me passing the option -s i
.
Here is one such MP3. I run loudgain
on it which returns with a successful exit code:
$ loudgain -I 3 -S -L -k -s i '01(51) Allegro (1).mp3'

Yet no tags are written and the file's modified time hasn't changed either:
