Before the 33 rpm vinyl album, there were 78 rpm albums, with several (usually 4) discs packaged in a single unit. I am tagging one of these albums now,* downloaded from the seemingly endless number of 78s collected by the Internet Archive.
I want the album artwork "front cover" to be displayed when I play the song, but where available I also want a photo of the label inside the mp3 file. There doesn't seem to be a proper category to assign these label photos — for example, "label." For now, they are "other," but is there a way of adding a freeform tag to the options? If not, what is the protocol for requesting an this feature from the vast (ha!) development staff at mp3tag world headquarters in beautiful Dresden?
