If you like screaming music check out Underoath, Atreyu, Chiodos, Alexisonfire, or Norma Jean

Some mellower alternative bands like Saosin, The Recieving End Of Sirens, Rise Against, Senses Fail are all really really good

idk im really bad at giving people advice on what to listen to, cuz everyone tends to have their own preference, but i try to help when i can
