Ok, I tried that, but it didnt work. Right after prepareToPlay, the
EngineController calls `play(track.playableUrl())`. Since the playable url
is being retrieved, the track playableUrl is still empty. So Amarok stops
the playback. I need a way to make the engine wait for the url to be
retrieved, like in MultiPlayback:
if( m_multiPlayback )
{
connect( m_multiPlayback, SIGNAL( playableUrlFetched( const KUrl &
) ), this, SLOT( slotPlayableUrlFetched( const KUrl & ) ) );
m_multiPlayback->fetchFirst();
}
