Screamo? That's a soft term to give to what you're referring to. Umm...if you want some fast paced rock that's not too alike Breaking Benjamin or Rise Against and isn't depressing, I'd recommend Starset. Fairly new. Or Thousand Foot Crutch, Red, ect. Hip-Hop, ehh. Maybe some Young Jeezy or Drake (Not his RnB songs though). If you're interested in Pop Punk (WARNING: Like three depressing songs cover this genre). Probably like Blink-182 or Yellowcard. For "screamo": Amon Amarth is a good start.
This may sound like a very harsh band, but its very good and I applaud them much. Listen to Five Finger Death Punch. Some of their most popular and easier songs are Far From Home and Bad Company. But If you want something a little deeper then I suggest Wrong Side of Heaven or American Capitalist. If you want something lighter then that then I suggest Fallout Boy or maybe even Imagine Dragons. If you need more I have a list of 300+ bands to browse through that I listen to.
ASKING ALEXANDRIA SUICIDE SILENCE CHELSEA GRIN BRING ME THE HORIZON YEAH totally not screamo or metalcore, these are all good rappers
What about Falling In Reverse? It may be categorized as screamo but many songs have rap entertwined and have more of a rock beat
