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.
The way all your words and sentences come together gives your script a distinct written tone. Combine that with a specific speaking tone to create an on-hold message that reinforces your brand and product set. Selecting the correct tones will ensure your intended message is communicated effectively. If your target market is the younger generation, then a tone which embodies fun and excitement would be most suitable.

– Sorry, I can’t be everywhere, and sitting by the phone ready to take your call, just isn’t going to happen. The best thing to do is to leave your message and not be offended that I wasn’t able to speak with you. Thanks.
