Why are the lyrics in "screamo" and other popular emo genres so self-centered and full of pity?

'Emo' music as you call it, is supposed to deal with people in pain. Why judge it? It's just the type of genre. It is especially relatable to teenagers, are they are experiencing a lot of angst, and like to identify with the music they listen to.

But people interpret emo in different ways. There's the stereotypes, such as my chemical romance, then there's what emo USED to be, such as Sunny Day Real Estate. It is just like any other trend or fad; you get hipsters, preps, indie, goth, etc.

I don't see what's so hard to understand.

I'm a teenager, and I do occasionally listen to this 'emo' music, although the term I would give it is post hardcore. However, I usually prefer metal.

Um, that's the whole point of emo, bro. It's supposed to be melodramatic, first-world problems. And emo bands have been like this since the 90s. Listen to Sunny Day Real Estate or Mineral for example. They sound like teenagers because they're trying to. The name emo originated from emotive hardcore because of their emotive vocals.

Just listen to the brutal guitars you stupiddd motherffffuccker
