How annoying is this app?

Teasatron is a happy little maggot that likes to sing for you.
Just record somebodys name and Teasatron will insert it into a song about that person, a song that get’s on that persons nerve, but in a happy fun way!

All you need is an iPhone or iPad or an iPod with a microphone.

As an added bonus, you can also annoy your friends in French, German and Swedish.
