i do yes! i listen to vocaloid a lot, and have been for a long time, although i guess it doesn't really show, it's been years since they were my regular drawing muses. back in the day i immediately fell in love with rin and len, and my favourite voice was gumi. nowadays i still like them, but those voices aren't used as much anymore. my favourite new voice is kafu, but imo the best songs feature v flower.
