Heart pieces come from The Legend of Zelda series, where Link collects scattered pieces, usually four, to form a new Heart Container and increase his maximum health. The pickup jingle became shorthand among players for finding a secret or earning an upgrade. As Zelda clips, speedruns and fan edits spread online, the sound moved beyond the games into general gaming edits. It is still used because its meaning is clear without explanation: something rare was found, health went up, and the player moved forward stronger than before.
