Trying To Mark An MP3 File as Explicit

[Farhan_A03]

So I've added 8 songs to my Spotify useing local music files and all of them are explicit but they're not showing the explicit thing in spotify. One of them is and I think I need to edit the MP3 and add an explict tag or something but I don't know how. I've got a thing on my computer caleld MP3Tag which can probably do that. Does anyone know how I can mark it as explicit?

As far as I am aware, Spotify does not support explict song tagging.
