I gave you a list of the composers and years of each kirby game's production because on the wiki's site
you'll notice that there's mini games for each section of the game. And my guess is that they didn't produce any original music for it, as you mentioned. If that's the case, you're going to have to credit each composer for each tune that you arrange.
Goodluck, and godspeed.
