There was a game for the SNES called "Barkley Shut up and Jam!" It was a decent game, fairly good graphics for the time. However, the title was very memorable.
It (along with Space Jam) inspired a fan made RPG titled "Barkley Shut Up and Jam: Gaiden." The soundtrack was all Space Jam remixes. It very much popularized the idea of Space Jam remixes. The game is legendary.
Oh my god.
I was working on this before. Too bad my project was deleted along with my hard drive :(
At least I have a demo of it here.
(your album art is almost exactly the same as mine here :P)
Let me commentate on yours:
Overall, your (lack of :/) structure makes this slam sub-par. Try matching up motifs in the slammed song with specific things in Space Jam. For example, match up the main motif with the main motif of Space Jam (which is COME ON AND SLAM). If there's a structure change in the song, you'd expect there to be a change in Space Jam too.
You might try DaVinci Resolve 12 from Blackmagic Design.
I haven't used it yet but plan to when I get my new computer built. But I've heard really good things about it from /r/VideoEditing and a few people on /r/letsplay.
