Though I'm not the journal writing type, I'm forcing myself to write this one. I think I'm going to get Dj Hero, it looks really fun, plus I'm big fan of Daft Punk(:
Activision is already working on the sequel and there are rumors circling around that DJ Qbert's in it. Because of this I've thought about what songs should be in the game, so I here's a list of mash-ups I found on youtube that might make it in some form in DJ Hero 2.
