MPL metatag in playlist??

How do I get the metatag from the MiniPlayList in the "on air - now playing" inside Raduga.
So that the miniplaylist file is visible in the html when it is uploaded.
I use the miniplaylist with the Requester from Stéphane but on the playlist you only see the name "request" and not the song that is requested.
Does somebody have any idea??

Thanks DjB.
