MP3 Meta Data apps

Not sure if this is the place to post this, but I’m hoping.

I’m looking for a free MP3 meta data tagging tool. I’d like something that can search online for specifically “genres” for the files. However, I don’t necessarily need dozens of genres. I’d like to be able to set my own and let it draw from there.

Is what I’m asking available? I welcome suggestions

Thanks!

I use kid3 which is extremely flexible.
