Title: MC overwriting the Track Count & Disc Count MP3 tags
Post by: prod on May 05, 2009, 08:09:04 am
I set these tags in iTunes (it must go into a tag in the MP3 file itself) but whenever I change something in MC they get overwritten and I have to redo them. I'm guessing this shouldn't happen - but is it a problem with iTunes using non-standard MP3 tags or MC not respecting a standard? I'm aware I can't see these tags in MC, it would be very nice to though.

In ID3v2 tags the format is x/y ("track number/total tracks" & "disc number/total discs").

If the tagging program doesn't write the "total" part when it writes track or disc numbers it will not be preserved.

Where were you when I requested the Total Tracks and Total Discs fields? I didn't get any support:

Then it appears that MC is not writing these "total" parts ... which is a little surprising.

The ID3v2 tagger should preserve any totals.  If it's not happening for you, please send a sample file (before the problem) to matt at jriver dot com.

Thanks.

This will be fixed in a coming build.

It was trying to preserve the original count, but it loaded the count _after_ removing the original value.  Sometimes it's the simple things.

Sorry if it caused you any grief.

Great thanks only very minor grief, no worries.
