Is there a reference for flac tag names? The tagging utilities seem to allow me to add my own made up ones but I'd rather use whatever standard might be current. The missing tags are source, set, etc. Disc doesn't really map to set. Source in the comment tag gets confused with guest artists in the comment.
Is there any tool that will run live show tagger batched against a directory tree? Something to infer artist from the directory, album name from date+venue+location, etc?
I know this has been asked to death but search wasn't turning up anything helpful.
