"A" no doubts, it matches perfectly with Opera GX and it sounds futuristic, epic, the melody is just a master piece, creates an amazing atmosphere. Anyways I still prefer the one you use for you adds https://www.youtube.com/watch?v=Uv-jwjKxZsk this one is futuristic and the sounds are made so perfectly, like a drug, the perfect dosis of energy and very original sound. Im using Opera GX becouse I was catched by this music of the video (I´m sorry my english).
