Put it near the end of an edit, after the build-up has finished and just before the final image or result appears. Open earlier with a quieter backing track, then let this clip close the sequence, and add a correct answer chime after a quiz win or an air horn for a big celebration.

The clip is the chorus of 'I Believe I Can Fly', about sixteen seconds of a powerful lead vocal singing the song's hopeful refrain over a swelling backing arrangement. It feels triumphant and encouraging, like a moment of lift after a long build, and it works best as a burst of confidence rather than a quiet background piece.
