Just because many people associate a certain song with a feeling doesn't mean it causes that feeling.
Hell, I like to listen to really angry music when I'm really angry. It doesn't alter or inspire my feelings, but it helps me to recognize em better.
It's a sad song, but if someone kills them self while listening to this song, they were intending to do it anyways.
Baa baa black sheep have you any booze? No sir, no sir, I'm a....sheep~
