Mine is also K.K. Waltz. I like it because I have a darker gothic-themed town, and it goes really well with my house. It also sounds good on the music box, radios, and the record players so it’s versatile!
I love K.K. Sonata. Playing on a record player, it sounds very classy and elegant and I especially love it when sung by villagers because it sounds both cute and eerie. There is nothing better than an island stroll by night with Olivia serenading it Sometimes I mix it up with K.K. Lament, but Sonata really is my favourite.
my favourites are hypno k.k., animal city, stale cupcakes, k.k. birthday, chillwave, k.k. lullaby and k.k. synth, but i’d say that my #1 favourite right now is either k.k. birthday or chillwave.
