Nice breakdown and a sweet melody. I wish you could here the drop in this preview, but from the total length of the track it seems that there won't be any real drop anyway, so I am not that excited to hear the rest.
If I had to judge from this whole trilogy by Brendan and Cat Martin, this piece is good but only good because I don't feel (even after a short excerpt) something new and fresh that was shown in the previous songs White Rooms and Crashing Over. This is my opinion only.
