Classical Ringback

So there's another thing that I've noticed at work, and that is the choices people make regarding ringbacks. For those of you who, like me, do not necessarily stay hip the curren jive, ringback tones are what you hear when you call someone rather than the standard ringing noise. Some of them are interesting, some of them are obnoxious, but they're all a personal statement by the person you're calling. I've heard the How I Met Your Mother song, which pretty much made my night. I've heard some club songs, and couldn't resist swaying to the beat. My supervisor, of course, always tells me to status it as an answering machine and move on (It's a tie whether she tells me to do that more, or to read our company responses verbatim), which I do sometimes if it's an annoying song, but most of the time I'll listen for at least a few seconds. People who have ringbacks set up on their phone deserve to let (car rental company) know about their experiences, too.
Back to the point at hand, I've heard some pop, some rock, a fair amount of country, and a surprising amount of classical. But here's the catch with the classical music, it's the same song. Every single classical ringback that I've heard in my two weeks of calling has been THE SAME SONG! I couldn't tell you what song it is, specifically, as I'm not incredibly familiar with the genre, but it sounds a fair bit like Vivaldi. I hear Garth Brooks, and Alan Jackson, and Toby Keith. I've heard Ke$ha, and the Black Eyed Peas. I've heard Metallica, Jimmy Buffett, The Rolling Stones, and at least four different songs by the Flaming Lips. But out of classical music? One song. Period.
The one thing that I can most certainly not tell you, of course, is WHY. Why this one song? I'm interested in getting some conversation going here. Why do you think they're all the same song? What do you think about ringbacks? Or about telemarket researching as a profession? Or, for that matter, about this blog as a whole?
