Thanks KM, but...

"Go find ~/Library/Application Support/Cog/Default.m3u
(where ~ is your Home folder)"

There's no 'Cog' directory in my Library/Application Support folder, so i can't find this file.

Also, this is not quite what i was after. This is talking about having the playlist clear when you close the program and restart it. That's a step in the right direction but I was really talking about it just clearing whenever you open a new file. I don't want anything staying in the playlist after i move on to playing something else.
