On opening multiple mp3 files

1. Hit "Open music files"
2. When the file selection menu opens up, select multiple .mp3 files and import them.
3. Error happens, and no music is loaded in.

Edit: This actually happens when you open even one music file, too. So basically, it's broken... Never mind. That was a different error than this one, and it says it may be because my Atom editor is out of date.

Work-around:

1. Click "Clear Playlist"
2. Add music files successful

Issue:

  filesBrowsed: (e) =>
    files = e.target.files
    if files? and files.length > 0
      ...

files? is converted to files != null and undefined is still uncatched. @sdinesh86 @jamesalbert But i don't know, how to fix it. :-(

Fix in progress..
