When an obsessed fan sent Sarah McLachlan a plethora of love letters, instead of recoiling in fear, she penned a song. "Writing the song 'Possession' [about the fan] was very therapeutic," the Canadian singer told Rolling Stone. The stalker sued her for the unauthorized use of his private letters, but the lawsuit was dropped after he committed suicide. "It's funny, because almost every letter I get these days, the writer says, 'I'm not one of those psycho fans.' But ever since then I haven't gotten any letters that were freaky like that, which is great, because I used to get them all of the time."
