Regarding the time remaining in the current song, you should be able to calculate this by using the "position" and "duration" fields in the raw API xml (http://localhost:8088/API) and looking at the input which contains the song that is currently playing. Both numbers are in milliseconds, and contain the current position and the length of the file. You could then have a function which converts the remaining time (duration - position) from milliseconds to minutes/seconds.

Unfortunately I do not believe there is a way to retrieve other list items via the API - I submitted a Feature Request on this some time ago but I don't believe there was enough interest to get it implemented.

I found a way to do it in the forums...

using powershell
