The originals definitely have their own style compared to the other modern Kirby games, and while it's not as distinct as Planet Robobot (obviously), the increased variety of instruments gives so many songs their own unique flair. I'm sure that some would say that it's a bit bloated, but getting so many great Kirby tracks in such high quality is totally worth it. I think it's great that so many tracks made it in, even those that aren't KSA originals.
