I'll chime in too... I've found nothing with the power of this program. I need something to modify the tags of the plethora of podcasts that I listen to so that itunes will properly order and allow me to control the playback speed.
I'd love to be able to do this with doppler and a command line interface to mp3tag.
Necro-bump I realize but I've so often desired this feature. The ability to launch Mp3Tag with a target file/directory and apply an action via a command line option from anywhere would be a boon for productivity.
Being able to add a context menu item from foobar2000 directly, or via Explorer into Mp3Tag and apply an action would be a fantastic addition.
Just dropping in to say that I would also love to see some command line options implemented someday, or at least just one - running an Action on the specified folder or file.
My media player is very finicky about tags, to the point where one bad tag completely corrupts its database and all albums and tracks are given the same name. MP3TAG has eased much of the headache of making sure this doesn't happen.
I have been refining my custom Action to make this automated for a while now, and its unfortunate that there's no way to trigger it from Explorer.
Great thanks to the dev and keep up the good work.
I didn't make a donation so far as i am using the tool for about a week now. But count me in with €40 if numbering and running actions could be done via command line.
