Made famous by George Costanza as you can see the clip here, the answering machine song may seem like a good idea. It's out of the box, unexpected, and definitely a novelty, but unless you're in the music business, it's probably not a good idea. You'll definitely irritate your mother (or anyone else important who calls you frequently) and you won't make a good first impression with your message.
Using your cell phone to record a voicemail message isn't always easy. Between remembering what to say and getting the right timing, it's tricky. But your phone does have a playback option, and it's easy to listen to and review your message. For some people, though, cutting off the end of a message is a funny way to trick people and catch them off guard. In most situations, callers won't know it's intentional and will think you're far less than tech savvy. Definitely not an impression I'd want to make.
