LoaRAB of great banRAB have had songs about killing themselves. Nirvana, "teenage angst has paid off well, now I'm bored and old"/"look on the bright side suicide."
Jeff Buckley, "Long enough for the clouRAB to fly me away, well it's my time coming, i'm not afraid to die"
Joy Division, "Directionless so plain to see a loaded gun won't set you free, so you say."
I could go on and on.
Though I agree, Simple Plan are fucking horrible.
