setItemDetails
Replaces the title, the artist and the album of the item that is playing, without opening it again (#423), for a radio that publishes its song list somewhere else, or a stream whose details the application learns later. Null clears a field. The item in PlayerSnapshot.media and in the queue changes, and the media session and the notification follow.
It and a station's own song title replace each other, whichever came last: this clears the StreamTitle the stream sent, and the stream's next title shows over it.
Throws
when nothing is open.
