While playing a .mp3 file, if you switch to the Now Playing view and press Find Album Info., a black window opens instead of the search results?
If the .mp3 file has NOT been added to your media library, you will experience this behavior.
To fix this problem:
1. Play the .mp3 file.
2. Press Media Library.
3. Press Add.
4. Press Add Currently Playing Track.
Now that the track has been added to the media library, when you press Now Playing and Find Album Info., the search results are displayed.
