I don't think that Zombie Nation entry belongs on the list for 2 reasons:
Besides, does the MSX version even have the tune ripped off by Zombie Nation? Watched a <9min video on youtube, which didn't have the ripped off bit, on subgames where C64 version has it. Need to check the game itself later.
It has the tune 
As fan or Mr. Zombie (Flo) once I played the game just to listen to it.
Yes, apparently the MSX version has shuffled the tunes a bit 
Anyway, I'm not sure, but I don't think David Whittaker did any music for MSX. This, of course, would mean that someone else must have converted it later.
Why would this be more significant in this case? It makes the C64 version the "original" AND the likely source, where Kernkraft 400 was ripped from. Every article I have seen mentions C64, not MSX. Or perhaps Zombie Nation just didn't want to say they based it on MSX instead, so they wouldn't have to pay for the guy behind the conversion aswell? 
(as is the case with the more recent Acidjazzed Evening ripoff - original creator was paid off I guess, but the guy behind the C64 conversion that was ripped wanted to fight).
But in any case, for the reasons I already mentioned, I propose either:
-Removing Lazy Jones, as this Kerkraft 400 case doesn't belong on this list as it's "wrong way around".
OR
-Modify it to mention 99 Red Balloons, Fade to Gray etc. instead (as some subtunes are clearly inspired by them).
