Sonic the Hedgehog launched in 1991 for the Sega Genesis, known as the Mega Drive outside North America, and introduced Sega's blue mascot as a rival to Mario. Masato Nakamura, bassist of Japanese band Dreams Come True, composed the soundtrack, including this title theme. The melody became closely tied to Sonic's identity during the 16-bit era and has been reused, remixed, and referenced across later games, shows, and fan videos. Its short, memorable hook keeps it popular online as a shorthand for 90s gaming nostalgia.
