My Question or Issue

 I've tried to play local files before, with no success. (.mp3)
Last night i tried again and suddenly it worked. Finaly. (.mp3)

But when i tried to play same files today it's no reaction when i hit «Play» on top or on each song.

Yes, the files is fine and working everywhere else, but in Spotify it's a problem obviouse. Why is this and what can you/we do to fix this?
