Once more, something we're not really proud of
The name of the girl singing this song is Joy. I believe she's 7 or 8 years old. About a year ago, she wanted to have a song of her own and therefore asked her aunt, who is a songwriter and owns a record studio, to write her one - "Schnappi" was born. The song was downloadable for free for more than one year when suddenly some radio station became aware of it and started to play it from time to time... and soon (almost) everyone did. Joy has been to our edition of "Top of the Pops" and other chart shows and given a number of interviews already. It seems like she's a pretty normal, sweet little girl, but this song is probably the hottest candidate for the "menace award 2005" should there ever be one...
Meanwhile, there's been a lot of fun made of it, including various faked cover versions, meaning someone took the song and made it sound like another musician or band played it -> downloadable from your second link for example
