Man, this is straight paranoia. The only similarities in a lot of these songs is that the same video game song was used and it was aligned with generic techno beats. You do realize that people are allowed to use 1-2-1-2-1-2-1-2-1-2-1-2 type beats with video game songs without OCRemix'es approval.
And honestly, OCRemix is about remixing music, yet someone is getting angry about this guy remixing THAT music, seems kinda hypocritical since you are both equally non-creative technically.
Most musicians that I know personally, especially musicians trained in jazz, could do things like this rather quickly. The rate at which they appear is no coincidence, with the right gear, you can record stuff without having to do much mixing on it to make it as passable as these tracks are. He sounds like he is trained in Jazz music, which explains all the seamless soloing.
