"The Words Best Friend Become Redefined" by Chiodos and "Rum Is For Drinking, Not For Burning" by Senses Fail aren't too hard. And any song by Hawthorne Heights is easy.
id say start with a hardcore/screamo bands slow songs

like if you like underoath then id say writing on the walls (ive never tried playing this i just think it doesnt sound too complicated)
or if your more into atreyu go with lead sails paper anchor or even the remembrance ballad

+1 to senses fail
Anything by From First To Last really. Most stuff by Chiodos isn't really complex. There aren't really too many complicated screamo songs.

god placed the fossils in earth to confuse the humans into thinking that earth is older than it actually is, therefore, making men try and think outside the box....

just kidding, there is no god
