Any awesome song suggestions?

I am getting tired of the same songs on my itunes playing over and over. I want some new music. I like "Changing" by the Airborne Toxic Event, "There's A Good Reason These Tables Are Numbered Honey, You Just Haven't Thought Of It Yet" by Panic! at the disco, "If it means a lot to you" by A day to remember, incubus, mayday parade, and I love Lights. Just a lot stuff like that. I was wondering if there are songs similar to these that maybe are not mainstream and are freaking great. Much appreciated :)
