 #### Translating it in to a step-by-step list:
 
+- Check if our stream is running and start if not
 - Define the path and name of our pipe using a pre-determined prefix and random number suffix.
 - Create this named pipe with mknod.
 - Play back the stream using mplayer; outputting PCM to the named pipe, resampled to 8khz, and downmixed.
 - CAT this pipe to stdout.
-- Delete the named pipe.
 
-Originally this script had things to find existing pipes and delete them. Storing them in /tmp means they'll disappear on reboot. *If things go right* you won't need to constantly start and stop anything. You can however always look at running processes and see which pipes are being used. 
+The previous version borrowed heavily from the "it works" method. A couple things are different now:
+
+- removed mplayer -playlist option since that was never a problem
+- changed to -softvol for no apparent reason
+- added if statement to handle checking of ices2
+- removed the statement to delete the pipe as it wasn't needed
+
+The addition of the if statement solved a problem of making sure ices2 is feeding my icecast. I attempted to do this in systemd and it just failed. I may have figured out why, but doing it inside the script doesn't hurt and is easier than mucking around with systemd.
 
-The original version of my Classic Hold used this, in combination with icecast2 and ices2.
 
-But surely we can do this without getting icecast ivolved....directly with applications.
+But if you're just feeding a bunch ogg files to icecast, can't you do it with without icecast and using a playlist?
 
-Oh...sure...we can...***but holy cow***.
