Brian Eno's six-second Windows 95 chime played at boot for decades. Andy Hertzfeld's 600 Hz beep kicked off every Mac since 1984. Ryuichi Sakamoto made Dreamcast's startup jingle, but Sega didn't even put his name on the box. Elwood Edwards recorded "you've got mail" in his living room for $200, and ended up as the most-heard voice on the internet.
