I think someone needs to invent a viable multitrack medium. Lets say an 8 track on a cd, so you could take different parts of of the mix live. I think that could be quite intresting. As for cds that beatmatch themselves - its already available, and im all for it. Why should you have to beat match? It doesnt make the music any better, all it does is distract your attention away from being creative. Since most people can beat match pretty decently with a bit of practice, i hope we see an end to this anoyance as soon as posible.
