Streets of Rage was released by Sega in 1991 for the Mega Drive and Genesis, becoming one of the defining beat em up series of the 16-bit era. Its soundtrack by Yuzo Koshiro drew on house, techno and hip hop heard in clubs at the time, which was unusual for games then and helped the music gain respect outside gaming. Clips from the series still circulate in retro gaming videos, remixes and soundboards, where the opening themes instantly identify the franchise and its street fighting setting.
