Payload of the jitQueue:trackChanged event.
A track of the shadow playlist started playing, a replay of the current track included. trackId and title are the session's current track as jitQueue.playNow or jitQueue.enqueueNext named it. Tracks inserted by jitQueue.preloadBatch have no identifier: playing one leaves both unchanged, and both are empty once a batch has started playback. The JIT events go to the page that started the session, with jitQueue.playNow or with a jitQueue.preloadBatch that started playback; when that page is gone, to a page under the same top-level window, and else to the main window's page. A page whose session another page started anew hears nothing more of it. Before any session has started they go to the main window's page.
