Yo why so emo? Your being really emo right now joybus and i don't like it.
A genre of rock music that emerged in the 1990s and got popular in the underground music community through bands like Sunny Day Real Estate, Cap'n Jazz and Mineral among others. The genre is characterized by introspective, confessional lyrics, emotive vocals and indie rock-esque instrumentation.
With the beginning of the 21st century, emo started to die out as people were mislabeling pop-punk bands such as My Chemical Romance and Dashboard Confessional as emo. However, the genre has seen a sort of revival in recent years, with bands like The Hotelier, Sorority Noise and Foxing getting more popular in indie circles.
The word is also used to describe a certain lifestyle, however this is not related to actual emo music.
What's your favorite emo band?
Emo is defined in multiple ways. It isn't just some stupid music of genre, nor is it people who self harm. Emo is a character trait. It's a genre of music. However, some "normal people" listen to it and don't even know it. Emos aren't all mean, and the ones who are have a reason to be. Some are really nice, but like I said it's a character trait. It depends on the person.
