In my opinion, something that helps make many EDM tracks stand above mainstream pop pieces are the vocals. While Katy Perry, Lady Gaga and other artists have great voices, to me, they don't stand out and give me chills like many voices present in EDM.
A good voice can give me chills. Pair it with piano and/or an acoustic guitar and I get chills to the point of goosebumps. I can feel the beauty of the music resonate through my body. That's exactly what this acoustic version of 'Gold Skies' by DVBBS and Delora does to me and I'm sure it will for you to. Debates set aside, there's no denying that when an artist releases acoustic pieces like this that the talent is there. We hear it. We feel it.
