I'm new to audio surf, but I am a metal head myself. I sure do listen more violent music as some would say. For example a band called "Innerguilt" they are pretty new, they are from the middle east. A song that I played while on Audio surf was "Burn" from them. I find this song to stimulate my interests in this music. While playing this, I had an idea that it would be pretty cool that there was flames or fire for the theme of the game. Instead of it being all colorful and seizureistic, I don't don't find the current type of colorfulness in the back round to be very relevant to the type of music I listen to. Don't get me wrong, I think this game is absolutely amazing at the fact you are able to load your own music and play it by "surfing" it. I just think it would be nice if there were more Evil themes, or at least more fire. The little bars you run into that pertain your score is fine, I get that...but I'm mainly talking about the back round not the surface your surfing on, but if it's possible I'm asking there to be more sinister themes, that deal with death, fire, or hatred. Possibly add skulls in the back round that fade into fire or make it seem like your going through hell or a hell portal...ehh, I think you get what I'm trying to say by now. I certainly think this idea would satisfy other metal heads out there that listen to the stuff I do as well... I'm on route 666!
