I'm no music fascist...
...but I prefer guitar music like melodic punk or skate punk (NOFX, Millencolin), acoustic stuff (Nikola Sarcevic, Chuck Ragan), hardcore (Ignite, Walls of Jericho, To Kill), screamo (Some girls, Dufresne, Nothing Gold Can Stay), emocore (Silverstein, Boy Sets Fire, Funeral for a friend) and other stuff like Billy Talent Electro, Funk, Hip Hop even gets my ear, depends of my mood...
