Multiple genre tags

Hello,
I don’t know if it’s possible, but i would like to add a custom genre to some tracks.
For example : from lastgenre : “Jazz” but I would like to add “Modern Jazz” too from command line.
Is this possible ?

Thanks

Look here.

In fact, I would like to add it from the command line, not automatically.

Look here then.

Hi! We don’t currently support multiple tags of any sort. See this issue, for example:

Ok, thanks!
