Thanks to Robin and William for their keepalive scripting fu. Icecast/IceS are
very crashy, and this script has worked pretty flawlessly for me. I also added
some stuff to build a list of the last ten songs played.
I'm using the version of the script that checks in the stats.log file for
the source every two minutes. While it's doing that, it also figures out the
currently playing song, and adds it to a list of the last ten songs played, a
text file called 'songs.log.' I use PHP to parse this text file into a
Web page for my site.
There's probably a much better way to do this, but it seems to work pretty
well for me.
Thanks again, y'all.
Matthew
