The American Idol theme song, the one that goes “tanan-nanan-nanan-nanan” every time the the American Idol logo is shown, is much more a mystery than an actual song. I have tried searching for information about this, but nothing is to be found, which makes this post more of an information plea than a resource. So people, hit the comments if you have any information.
However, there is a complete (or long) version in YouTube, and, if the video below still exists while you’re reading this, the original uploader posted a download link to it. Enjoy.
