I like vocaloid folk and fantasy music, I know my taste is so boring
Maybe some of you don't know Korean vocaloids, They are awesome and the particular Sagnoksu producer is amazing
Eight minute folk music with Mongolian style (SeeU)
This one has folk metal twist to it (SeeU)
Epic 16 minute folk music (UNI)
This one is also underrated Utaite, Lily singing "Soleil" by Toraburuta-P. I like the AkikoShikata-esque layered voices.
Another one by her and Re:, One who Falls in The Name of God by Kaoling.
