I searched around an found [ this ](http://www.macosxhints.com/article.php?story=20011108211802830)
article on the topic but of course wanted many tweaks of my own so I’ve
wrote the following script that should allow anyone to control iTunes in terminal
or via SSH remotely.

### Possible Uses ###
The implications are pretty neat if you think about it.

• DJ a party from a laptop, iPhone, or mobile with SSH
• Control your home or office music server remotely
• Scare the heck out of your roommates
