[Icecast] MP3 Tags in icecast?

[Hubert Gabler]

Hello!
Maybe this question has been asked many times before, but searching the 
archives of the last 2 years I did not find an answer.
I have installed icecast2 and darkice on a PC running on Ubuntu 12.04. 
Streaming works fine on both other PCs, players and even Squeezebox 
Radio. There is only one problem: the players do not show the MP3-Tags 
of the songs played.
Is this a property of the Icecast Server or did I miss something during 
installation?

Thanks for any suggestion!
Hubert
