TrackMetadataListener (beat-link 7.3.0 API)

```
public interface TrackMetadataListener
```
The listener interface for receiving updates when the metadata available about a track loaded in any player changes.

Classes that are interested having up-to-date information about metadata for loaded tracks can implement this interface, and then pass the implementing instance to MetadataFinder.addTrackMetadataListener(TrackMetadataListener). Then, whenever a player loads a new track (or the set of available metadata changes, so we know more or less about tracks in any loaded player), metadataChanged(TrackMetadataUpdate) will be called, with the currently available metadata about the track (if any) loaded in the player.
