I need new bands to listen to?

Im lookin for some new bands to listen too. The bands don't have to be necessarily new, just new to me. Some bands I like so that you can have a taste for what I'm looking for are Say Anything, A Day to Remember, Set Your Goals, Five Years Strong, Foo Fighters, Gravenhurst, Pion Pit, MGMT, K'naan, The Mars Volta, Yellowcard. Answers will be much appreciated. And if I can figure out this point system thing, I will reward what I consider the best answer with some points.
