from the top of my head utsu, pino, jin, task, furukawa honpo and toku are his friends. he likes common world domination and mushroom mother by pino & a couple furukawa songs (alice is the first one that comes to mind since he did a self cover of it) i didnt bother putting hachi on the list since everyone knows theyre friends but he REALLY liked rinne. he loves nbuna and also ill link my vocadb list of vocaloid songs wowaka likes (but beware its a little outdated)
