I'm a Vocaloid maniac and my collection is filled with them! Miku is waifu but I like also Megurine Luka, Yuzuki Yukari, Otomachi Una, Meika Hime/Mikoto, GUMI and IA.
Actually, I'm a big fan of japanese music. My tastes are rather broad - I listen pop, rock, metal, EDM and I love them all. I love bright and complicated melodies.
