Premiered by David Guetta and played by Armin van Buuren across his festival sets over the past summer, 7 Skies’ first release on his new imprint STANDALONE MUSIC is a high-energy EDM fused with melodic techno track with hypnotic synths and a beautifully executed emotional vocal in the breakdown. “Used to Know” is a well-known song between David Guetta and Armin Van Buuren fans who can finally enjoy the track in its official release.
