I have a story to tell. It's 100% true. Two or three years ago, somebody opened a site full of "experimental" MP3 files. The "artist" was called Zé Cabra, and basically he was singing over sequences. The site became more and more famous, as it was so hilarious. But then the site was closed, and a recording company took him and produced a CD. Everybody was laughing but the CD was a huge sale success, and nº 1 in Portugal. He traveled the country giving concerts, and charging a lot for them. You can listen to his main hit, here (exactly like recorded in the CD, but with lower quality):
