[SOLVED] tagValue Artist.merge does not work with certain tagUpdate file?

[simoncn]

The order of tag processing is as follows:

1) Tags are read from the audio file
2) Special tags (with names starting #) are added if present in either indexTags or itemTags
3) For each tag in turn, tagUpdate processing (if any) is applied to the tag, followed by aliasTags processing (if any)
4) For each new tag added by tagUpdate processing, tagUpdate processing (if any) is applied to the tag, followed by aliasTags processing (if any)
5) Any actions specified in tagOptions are applied in the order they appear in the tagOptions string
6) Any actions specified in tagValue are applied in the order they appear in the tagValue string
7) Any indexFormat actions in tagFormat are applied in the order they appear in the tagFormat string

This completes tag processing. Any displayFormat actions in tagFormat do not change tag values. They are applied to metadata sent to the control point when this metadata is requested.
