Cell Phone Funnies (Explainable This Time)

A couple of weeks ago, while waiting for my sister in front of my building for an errand we were going to run, I found a text from Rogers on my phone saying I could pick and download a free ring tone. Among the options was Julie Andrew's "My Favourite Things", so click I did, and my ring tone was downloaded.
I didn't get any calls for the rest of that day, but the next morning, as I sat down to work, I suddenly heard Julie Andrews singing at a surprisingly high pitch... I had completely forgotten. Instead of checking my phone, I assumed I had a window open on the Internet on some site that had audio attached, or that some pop-up was taking over my computer. I hurried to close all the windows, but couldn't find any pop-ups. Still, the singing had conveniently stopped (this, of course, was my phone going to voicemail). Twenty minutes later, she was back:
Rain drops on roses and whiskers on kittens!
Bright copper kettles and warm woollen mittens!

It clicked: that's my phone!!

I'm such a nerd.
