Some of the audio in my skill can be an hour long. These are talks and lectures. The option to have Alexa "introduce" the title and speaker before playing each talk in the play list would be great.
Example:
You just finished listening to a 30 minute talk and Alexa has already queued up the next talk in the series. When the first talk ends, but before the second talk begins, Alexa verbally tells the user the next items title and the name of the person giving the talk. Then the next talk begins to stream.
Obviously, you probably wouldn't want this for normal playlists, like songs, but for podcasts, talks, lectures, and more, it would definitely be handy.
