Maybe I'm turning into an old fart, but I'm getting severely annoyed with the "need" to fix something that ain't broken. "Personalizing" voicemail with someone else's music is just another way to annoy people who are calling you. It's very likely that this "special" music which you like a lot others may not be so crazy for. Another in the same vein of annoyance is the service where you call someone's number and instead of the familiar ringback tone you get the person's choice of music blaring in your ear until such time as they decide to answer. We know the reason for these services ... to make a buck.
