International Anthem is a track by British dubstep producer Flux Pavilion featuring Doktor, and this short excerpt is the part most often shared online under the name airport music. The nickname comes from how creators use it: the rising, hopeful sound fits footage of terminals, runways and arrivals far better than a generic background track. As travel vlogs, holiday reels and montage edits reused the same opening, the clip became shorthand for setting off somewhere new, which is why it still appears whenever a creator wants instant wanderlust without a long musical intro.
