This was probably said, but I'm gonna say it anyway.
You don't have to use techno, and if you're gonna use shitty screaming metal, pick a better song. At least a faster one. The replays are ok (I'm not going to insult your playing since I suck myself) and you don't have to use alot of effects to make a movie great. Using un-orthodox music and tempo can work, if you at least pick a good song.
Also, buy or "buy" fraps, seeing the watermark at the top makes me think "noob movie" right away. :|
