I saw a TV show on Discovery Channel that I think was called Ten Methods.
It was about a forbidden song, that made 9 out of 10 people who listened to it commit suicide.
Anybody knows something about it? Because I wasn't able to find out anything about it.

Urban legend, there is no such song. If there was, there would be alot more people driving there cars of cliffs while listening to it on the radio

Are you referring to the urban legend of the song "Gloomy Sunday"
I remember reading it in a book about strange occurances, but im sure it is not true.

Was actually banned by the BBC for donkeys years, until recently...
