can u honestly imagine listening to this music when ure 25- 35? it's designed from ground up to appeal to the demographic of 12 - 20, screamo probably in the higher reaches of that.
It's all about teenage angst, but the reason why so many have contempt for it is because it's like eating sugar - we all love sugar as children (hell i'm 17 i love sugar) emo is like eating lollies, whereas metal and punk are still feeding the same sugar urge but are more like eating chocolate - where the food is not just sugar but also a mixture between milk and nuts and so on so forth. So emo and screamo is almost like limiting yourself even though your getting more bang for your lil teenage angst buck.
