"The success of 'Shut Up and Dance' has been pretty mindblowing," singer Nicholas Petricca told Fuse. "We have been ambitious from the start; y'know, we always hoped that it would skyrocket and take us around the world. It's amazing to feel like the song isn't just contained in America, that we have a life outside the states. It's really exciting to take it a whole other world of people."
