An interesting mash-up that I can't help but try out. Still being able to listen to cool music on FA, I came across SonicTweaker's "Night on the Dancefloor." It has a really cool upbeat and it does give the ol' school 90s Sonic feel to it. So with permission I was able to combine his music with Sonic CD's Metallic Madness (US past version).
Seeing that this is on a whim there's a couple of things I've notice. 1) There are breaks that will go to Tweaker's music due to not overpowering with the other song. 2) I tried to adjust the levels of certain parts on the songs since some parts originally overlap each other. 3)There are also key musical parts on Metallic Madness that I wish I can separate from the rest. But in order to do that is to play the parts myself on my keyboard or on Techno eJay if it the proper sounds. So this could be merged a little better. (I know, I have El Cheapo equipment =>.<;=)
