It is not that I feel much of Massive Attack grove here. The music here feels like a filler for voices, at least in the first part, while my perception of Massive Attack is that voices are just another tool to add expression to the sound. The second part is catchy, but in the end the whole song sounds repetitive. I would switch second part and the first places, and if that makes the first part unbearable, would think about removing or reworking that - adding silence, removing the repeating voice pitches, work with slowing down maybe. That is, if I compare it to MA, but that might not be your goal. Just my 0.02 cents. )
