Check out: http://svn.xiph.org/icecast/trunk/icecast/src/format_mp3.c
(function: filter_shoutcast_metadata). They look for a key name
specifically in the metadata, but since we're actually interested in
parsing the key here, it has to be a bit more open-ended.

Is this data anything that can be shown to a user? IIRC, it's just the
metadata interval, possibly bitrate, and the like.
