I don't find those animal crossing soundtracks particularly good. I think it's the limitations in the instruments. The remix is an improvement but not very compelling.
I cannot describe what makes a song good for me.
I hate grumbly voice metal, for instance, but when I heard
Kali Yuga for the first time I went apeshit trying to find it. It was RAC and very hard to find in HQ and it took me hours to find pure rips of the song online, which involved literally guessing URLs on random german review blogs to find them. When I did I archived it with lyrics I forced some random kraut from the forum to translate for me because I wanted to share it. I listen to it a lot still, because I know what the lyrics mean now, and I like the song even more as a result.
Sometimes a song just sticks. It's almost never a genre/artist thing.
