Genre Generator Action

I have another problem to solve to speed up track processing.

The pool use doesn't fill in their genre tags and it's the last step I do which waste's a lot of time.

I have reached out already and they have decided to let the DJ's fill that information in.

How could I go about automating this in mp3tag, so it could check the music databases and adding in the genres automatically?

As you mention "action" in the thread title:
The action to set anything into GENRE is "Format tag field" - or you select the files that should get the same genre, enter the genre in the tag panel and save the modification.

That's not what I'm trying to do.

Selecting and adding genres manually are not a problem.

I'm talking about having mp3tag check the artist and song title against a supported music database then automatically populating them.

So far the only way to get external information is the use of web source scripts.
AFAIK you can set which fields should be filled as soon as you have found a match with the help of the web source script.

Taking a peek at this, Discogs Authorization – Mp3tag Documentation

and this, Importing Tags from Online Tag Sources – Mp3tag Documentation

Yeah definitely want to build an action for this.

I understand how to build the action, but can you pull from a tag source for an action such as genre?

I'm putting this on hold because I found a tool that does exactly this via drag and drop.

No.
Web sources cannot be called via actions.

No problem I found a tool that solves the problem.

I will say that even though I have a tool to do this now. It stil would be nicer built into mp3tag.
