    tracker-extract-libav: Use 'date' instead of 'creation_time' for ffmpeg music indexing.
    
    Only use ffmpeg 'creation_time' tag for video indexing. For music files, this will be the timestamp of 
when the file was ripped rather than the year of release of the album, and will cause each track to get 
indexed in its own separate album.
