Adding my own songs to apple music

Hi,

I used to be in a band (years ago) and we recorded CDs etc. I want to be able to add these to my wife's Apple Music app. They're already on mine. I've added them to her ipad using icloud, but can't figure out how to add them to the music app, it's not one of the options, when it opens by default (in the 'Files' app)

Any help much apprecaited.

Kind regards,

Dom
