Playing downloaded content/MP3s through Spotify

[abrodar78]

Ok so... I have audio files... rare demos and such on my micro SD card on my phone.  With YouTube music.... not only can I do everything I can do on Spotify but... I can also access and play those audio files.  Everything on one app.   I love Spotify and don't really WANT to change programs and start over making playlists but I'd love it if Spotify would allow me to access and play my files through their app.
