The recommended way to create Vorbis comments from a field that has multiple entries is as follows:
If there are two composers for a track, enter them in dbpoweramp like this:
The resulting Vorbis comments should be as follows:
This is done properly for the COMPOSER tag, like the above example.
However, for custom tags, like this one, only a single Vorbis comment is generated:
Entering this information for a custom tag named PERFORMER, like this:
results in this single Vorbis comment:
I've asked Spoon to please always parse such entries so that multiple tags are created instead of one long one. So far, no joy there. We wish to be able to tag each track with all of the performer's names and instrumentation, but if only one tag is created for all of them, it becomes very, very long and may be truncated. This is an obvious problem.
So here's the question: Is it possible to write a script of some kind that will "inspect" all Vorbis comments for this spacing (semicolon followed by a single space) and create individual Vorbis comments for each element in the original long string of values?
The only other option appears to enter each performer's tag information, one at a time, using the Alt-T panel and the New/Edit/OK buttons in mp3tag. Naturally it would be best if this were done 'correctly' in dbpoweramp to begin with.
