How to script a shared itunes music track

[aicul]

I am trying to have an applescript that will play the first track of a shared itunes playlist. But when I run the script I get the error message : "iTunes got an error: Can't make some data into the expected type."

tell application "iTunes"
	set sound volume to 50
	play shared track "Music"
end tell

Music is the name of the shared itunes playlist.
