What artist am I looking for?

I have been looking for an artist for over a year now and still have not found who it is. It is driving me crazy, I spend hours looking on the Web and sometimes homework does not get done. I am not even sure what genre he is in. The details that I do know are that he has a higher pitched voice like: Anthony Green, Conor Oberst, Craig Owens, the Mars Volta, Claudio, Gorrilaz, the guy from Dance Gavin Dance, maybe Brand New, stuff like that. I think I might have heard a acoustic guitar, but it has been such a long time since I have heard it. The genre could be Emo, Indie, or Alternative. It is primarily vocal and my mom once complained that it sounded he was just talking. It doesn't sound like the songs are edited to make him sound better in any way. There is a great amount emotion in his voice as well and never does the scream like you hear in metal. Don't get me wrong, I love that ****. Amon Amarth is one of my heroes, as well as Kamelot, Flyleaf, Sky Eats Plane, Horse the Band...okay I am probably confusing you guys and going off topic but yea I like good music. If you guys could just name as many Artists as you can, that would really cool. And if you actually list the band I am talking about, I will love you forever and we can FB each other or whatever is appropriate, doesn't have to be, but it would be wise. Oh and I vaguely remember some of the lyrics. There was this one song, that he was talking about writing a song. "A song that will change the way that people think and how we..." Please help me!!!
