I mostly listen to emo, so here's a few emo bands/artists i recommend
Dashboard Confessional. Just a dude with insane talent. Great voice, that always gives me chills. Very calm, but catchy melodies and great lyrics. I recommend the songs Remember to Breathe and The Brilliant Dance.
The Used. They're great at building up tension in songs and then releasing it in such a satisfying way, like in their songs On My Own, or Yesterdays Feelings.
Taking Back Sunday. They're like the kings of layering vocals. The way they build up their songs is just so good. I really like their songsย One-eighty By Summer and A Decade Under The Influence.
If you'd like something a little more agressive i recommend Alesana. Idk how to explain them, but they're amazing. I really recommend the album The Emptiness, especially the songs The Lover and A Lunatic's Lament.ย
One punk artist i wanna recommend is Nina Hagen. Just very fun to listen to. She uses amazing techniques for her voice, and has a very addictive sound to her. I like the songs Das kommt weil ich so schรถn bin and TV-GLOTZER
