Unable to play some local files

[AndriFannar]

Hello,

I am having a problem with my local files on Spotify. I just put some new .mp3 files in my music folder and was going to use them in a playlist in Spotify. They show up in the "Local Files" in Spotify but I can't listen to them. I always get this message: "This song is not available. If you have the file on your computer you can import it". I use local files a lot since I listen to soundtracks from various video games that are not available in Spotify but this has never happened. I can see the files in local files in Spotify and they are in the same place as all the other .mp3 files. I can listen to them in iTunes and on my phone but not in Spotify.

Is there a solution to this?
