Female vocals, but more scattered. Think of Glitch Mob - Between Two Points (Ft. Swan) but have the vocals spaced out a bit more. The music kind of reminds me of She mixed with The Glitch Mob but yeah, I really do not like the rap vocals at all.
Get rid of auto-tune. If that is a part of your concept, I despise the concept. Still listening to the album, on track 6. Edit: If it weren't for the auto-tune, Some of Them Scream would actually be my instant favourite.
