'Gonna Fly Now' was composed by Bill Conti for the 1976 film Rocky and plays over the famous training montage where Rocky Balboa sprints up the steps of the Philadelphia Museum of Art. The track turned into one of cinema's most recognisable pieces of motivational music, and decades later it still soundtracks gym PRs, race finishes and underdog edits across the internet. This shorter ringtone-style cut keeps just the punchy brass fanfare and marching drums, the part of the theme everyone hums when something worth cheering for happens.
