Here's an example JSON file:

{
    "genre": "Metal",
    "comment": "More information at http://openmetalcast.com",
    "title": "Open Metalcast Episode 039",
    "artist": "Open Metalcast",
    "album": "Open Metalcast",
    "image" : "../omc.png"
}

And a sample execution:

tagging --json tags.json --target open_metalcast_039
