Audio type in "media area"

Currently only “images” and “videos” types (and maybe some others I don’t know of yet) are supported in the media area. But I mainly deal with audio files. I know they can be uploaded, have their own icon and can even be selected, but when selecting them the bottom right text shows sth like “add 3 images” - instead of “add 3 audio files”.

Would love to see this supported. Thanks!
