leading zero in *.m4a


As the title says, I currently cannot save tags of *.m4a files with a leading zero, as "01" to "09". For some reasons it really helps me to use "01" etc. instead of "1" etc.

I use currently use foobar2000 to workaround this limitation, hopefully I don't have much of these files.


Sorry but the Apple m4a tagging standard does not allow leading zeroes.
foobar also does not write a leading zero, if you reload the tag it is gone.

ouch, this is right... if I manually reload the tag in foobar2000, it is removed...
