 * through a Gst::Bus. You can listen for Gst::MESSAGE_TAG messages and handle
 * them as you wish.
 *
 * Note, however, that the Gst::MESSAGE_TAG  message may be fired multiple
 * times in the pipeline. It is the application's responsibility to put all
 * those tags together and display them to the user in a nice, coherent way.
 * Usually, using merge() is a good enough way of doing this; make sure to
 * empty the cache when loading a new song, or after every few minutes when
 * listening to internet radio. Also, make sure you use Gst::TAG_MERGE_PREPEND
 * as merging mode, so that a new title (which came in later) has a preference
 * over the old one for display.
