Replace missing streamable songs with locals

[Emdel]

Hi,

I used to listen to some songs that once were on Spotify (for example the French band Tetes Raides or Peter Gabriel) and that are now missing (because of label choices, I assume). I would like to replace these missing songs with local files on my computer. Could it be possible to sync the Spotify missing tracks details (album, artist, release date, cover art) with my local tracks so they could "act as" streamable files ?

I tried to do it on some of my local files (I named them properly, added the artist and album in the MP3 details) but it work on some of them but none of all of them.

Could you help me ?

Regards
