Reformat 'album' tag

[simoncn]

The @ line needs to match the tag value exactly with no wildcards.

This means that doing what you want for a large number of albums isn't practical using a hand-edited tag update file and you would need to have some automated process for creating the tag update file from your album tag values. Alternatively, there are tag update programs (such as Mp3tag) that have a batch processing capability for making changes like this across your library.
