Is there a way to only update the original release date in the song tag? Can anyone point me to a discussion on this. Havent been able to find one.
What do you mean by song tag?
Sorry it seems there are two questions that I’m asking:
How do I get the original or earliest release date for a song? The metadata crawlers is bringing back the current release date.
If I only want to update the field/attribute original release date and not title, artist etc - how do I do that?
How to change (add) only mood with Picard-Last.fm.ng
Not quite sure what you mean with “the metadata crawlers” and what software you have used so far. But if you use MusicBrainz Picard it will load and store the original release date in a special tag. Many players however do not support this tag, in this case you can script Picard to write the original date tag to the normal date tag by adding this script to Options > Advanced > Scripting:
Picard is not really the best tool for just changing a single tag, it is really meant to pull data from MusicBrainz. But if you want to do it you can set all tags you don’t want Picard to overwrite in Options > tags > Preserve theses tags from being cleared or overwritten… . You can find a list of tags in http://picard.musicbrainz.org/docs/tags/
I would strongly suggest to keep the MusicBrainz ID tags, though, as it allows you to easily retag your files again without doing all the matching again.
