MediaFlow adds a new media view for your library and playlists you can access from the View>Media Views>MediaFlow menu.
This works well with the FocusTrack extension. With FocusTrack the currently shown album will change when the track changes. If you would like the default album art image to look different you may want to take a look at the Vinyl Album Art extension.
If you want to change the background you need to change the styles in chrome://mediaflow/skin/flow.css The reflections should change to match the background color
If you have an album with multiple artists and want them to show up as one album, make sure all of the tracks have the same album artist property. This can be set when editing their metadata or inline the playlist if you add the album artist column. The album artist property is looked at first and if it doesn't exist the artist is looked at when checking whether tracks with the same album name belong to the same album.
Supports 1.9.3. Not as efficient as I would like, sorry about that.
