Haha, please. So it isnt emotional saying that your life suck and you want to die? well, ok. Anyways, you can't take it so seriously that all emotional music is emo. Emo has becomed a category based on teens and their melodramatic lifes. Again, here's an example from Silverchair:
I dream about, how it's going to end,
Approaching me quickly,
Leaving a life of fear,
I only want my mind to be clear,
People, making fun of me,
For no reason but jealousy,
I fantasise about my death,
I'll *********** from holding my breath,
THATS emo. Emotional in the meaning of "whining" to be honest. There are lots of beautiful emotional music out there that would not be in the emo category
