Local File show up, but don't work.

[AJAnimationsYT]

Okay, so here's the problem.

There's this album by Twenty One Pilots called Regional At Best. I downloaded all the songs (legally, don't worry) and saved them in my folder. I look up how to add local files. I get excited, because Regional At Best isn't on spotify.

So, I follow instructions. Go to settings, add source to local files, I select the mp3 files, and allow. I go to the local files in my app, on the laptop, not web player. I go on there, and see all of the songs. Perfectly fine. I click play to Kitchen Sink, and my app closes out. I try 2 more times. My app closes out. Could you help?

If you want details, I'm on Ubuntu 18.04, which is a linux distrubution.

Thanks!

Oh, and I realized another problem. I add the source, and it's all good, but the app closes. I said that. The other problem is, although the source is added, the local files don't show up, so I add the same source AGAIN for the files to show up.

Please help!

Thanks... again
