Local files not appearing under My Music

[SanderW1]

Hello,

For a large part I used Spotify as my secondary player, because I did not have premium and deleted all of my own music from the application since I used iTunes as primairy player. Since a few months I have a premium account and want to use Spotify as a primairy player but I cannot add the albums I locally have back to My Music.

I checked the settings and Spotify is looking for music files in the correct folder but they are not appearing in Albums or Numbers under My Music. Does anybody have a solution??
