So I have Optimum Voice hooked up so that the network e-mails me any new voice mails I get. I get a .wav attached to an e-mail. Since I'm working from home today, I forwarded my office phone to my home office phone. I got a voice mail this morning and I clicked on it when the e-mail came in. This, of course, launched iTunes and I listened to it. At some point after that, I downloaded a couple songs to my iPod.
This is how you end up in a situation in which you're minding your own business, listening to your iPod, and then suddenly hear a voice mail from work come through your headphones right after your favorite ZZ Top song.
