Vocaloid: Megurine Luka
Apple Music
Introduced two years after VOCALOID software first became popular in Japan, Megurine Luka's digi-voice offers users a slightly deeper set of female vocals to play around with. Her huskier tones work wonders over bouncy synth-pop as well as chugging rock, and her delivery lends a serious note to any subject, whether she's singing about first love or the dissolution of a relationship.
