We only support shoutcast/ice streams where the metadata is interleaved 
in the datastream every x bytes (where x is a number chosen by the 
broadcaster). My guess is the ogg stream doesn't comply with the 
shoutcast format and is probably embedding the metadata in a tag or similar.

To be fair to us Paradise themselves admit that some players can't 
handle the embedded metadata.

We have not included song titles in our Ogg streams due to glitches with 
some players (notably VLC & certain hardware players). Since some 
players don't have this problem, we're now providing Ogg streams that 
include song title metadata. Players that reportedly don't glitch on 
title updates are Winamp, Audacious, foobar2000, ogg123, Rhythmbox, and 
Songbird.

The good news is we don't glitch :) the bad news is we don't get any 
metadata for these ogg streams :(. I tried one of the mp3 streams and 
that played fine and also got the metadata. I didn't try but I would 
assume the aac streams will also work.

We use ffmpeg to decode the stream which appears to remove the metadata 
while decoding so it may be possible to get the metadata from there. 
There may be a callback we can attach to to get it?
