Abraham wants to create a commercial playlist for a local TV station at his church. TWiT uses Playbox to do this. He can also just use Automator on the Mac with AppleScript.
Automator is widely used in the Mac community and can make automated scripts without a lot of programming knowledge. It's all drag and drop and easy to create a playlist. He can do it by timing, sequence etc. Abraham should check out Automator.us for tips.
