Scorpion, Noob, and Ermac are the characters that all of the new and/or bad players gravitate towards. It's because they are so easy to use, it's like an "easy win" button. With other characters, you actually have to TRY to win. xP
I am embarrassed at how little of their stuff I've heard. It's basically Clouddead, Daedalus and... ****. That's it. I am useless. Recommend me some more music, sir. I haven't heard a ton of new stuff in over a year.
