I'd advise against using the "company's" equipment to do anything but work. Even listening to music online. Well, at least until you get clarification from your supervisor.

In any case, doing anything but work while 'on the clock' is a great way to get fired. Like browsing CD.

Bringing an iPod to work should be OK - ask a colleague, since in your environment data storage devices may be forbidden - and you can listen to music that-a-way.

The alternative has worked for me for over 1/4 century: Enjoy what you do, to the point that you like doing it. I don't need anything to distract me, I'm almost never bored.
