I disagree with the two other comments about the vocals being repetitive, I think they're fine for what the genre is. They drive the track as it goes on, Motif Melody Groove, all come from the vocal chops and I love that.
It's a fantastic track. The only critisim I would give would be to maybe create more segments like the one around 2:30 / 2:40ish, a nice break that lets some other elements shine, which we kinda see around 3:00 too, which is pretty nice.
I mean, it's a really great track all the way through. It's just not going to be something everyone picks up and appreciates.
