Its...some form of theme guy...to the rescue!
This code shows the number of the track currently playing and toggles to the name of the next track in the list after 10 seconds.
%ac%t(10.0)Track: %?in<%in|N/A>;%t(10.0)%ac%sNext: %?It<%It|%Fn>
Is there a way to disable the toggle when the last track is reached? I mean, there's no point then to display: "Next:" or "Next: nothing".
We can cheat here, somewhat. We can detect if there is a next track present in a roundabout way, by checking to see if it has a file name. Obviously you won't want the sublines to cycle a blank line either, so there's going to be a slight amount of code duplication, but, we can live with that.
%ac%s%?Fn<%t(10.0)Track: %?in<%in|N/A>;%t(10.0)Next: %?It<%It|%Fn>|Track: %?in<%in|N/A>>
Let me know if you have any further questions, be it regarding the above syntax or otherwise.
