Not Sure Where This Should Go

[Des0lati0n]

Just a random question, is there anyway I could make HLDJ do a command in console after a certain song is done playing?

Knowing the length of the song, you could create a script with a series of waits and execute the command at the end, but it's a bit unfeasible.
You can try other approximate solutions like setting up some commands to execute every time you start or stop a song: http://hldj.org/forums/viewtopic.php?f=6&t=150
