Sonic & Knuckles launched in 1994 for the Sega Genesis as the lock-on companion to Sonic the Hedgehog 3, letting players connect the two cartridges. Its 1-Up jingle, credited to composer Howard Drossin, reworks the game's main theme into a short extra life fanfare heard after collecting 100 rings or breaking a 1-Up monitor. Clips of the sound later spread through gaming forums, YouTube retrospectives and soundboards, where retro fans kept it alive as a universal shorthand for earning a bonus or second chance.
