ACTUALLY I CAN SEE WHY:

The authorities do not know exactly how many people have been killed warbling “My Way” in karaoke bars over the years in the Philippines, or how many fatal fights it has fueled. But the news media have recorded at least half a dozen victims in the past decade and includes them in a subcategory of crime dubbed the “My Way Killings.”
 
The killings have produced urban legends about the song and left Filipinos groping for answers. Are the killings the natural byproduct of the country’s culture of violence, drinking and machismo? Or is there something inherently sinister in the song?

Urban legend or not, the truth is that I'm not surprised. If there were a wave of "Unchained Melody Killings", or "Any Song by Whitney Houston Particulary That One From The Bodyguard Killings" I would understand too. Karaoke bars are evil.
