I have a ton of music in a separate library for albums with multiple artists, i.e. Woodstock, for one example. I need to go through that library and edit the tags for (Multiple Artist) is there a way, maybe a query, to do this versus opening each file one at a time?
When you say Library, do you mean a directory on disk? Or a true separate MC library? Are the files imported into MC?
Once they are imported into MC, if you can identify the with a directory path, or some other attribute, you can easily just search for that attribute to find them. Then highlight them all, open the tagging window, and set the [Album Artist] field on all of them in one shot. It's one of the great things about MC: Editing tags on thousands or tens of thousands of files at once is just as easy as one file!
If you need any more guidance, just ask.
Brian.
