I've gotten into Russian Vocaloid covers recently.
Well, since @maple shared a cover of "Koi wa Sensou"... One hour ago. xD This is the first time I enjoy human vocalists since the last J-Rock concert I attended one year ago. While Japanese is still my favorite "musical language", Russian might take its place if I find original songs that are similar to Vocarock songs.
Original song: "Suna no Wakusei" (Eng. "Sand Planet") by Hachi feat. Hatsune Miku.
