These days, between the mainstream successes of Dance Dance Revolution, SingStar, and especially Guitar Hero, music-based games are all the rage. Titles that would have been niche releases just a year or two ago are now mainstream hits - just ask Elite Beat Agents. Their current popularity also allows more obscure titles a shot at a major release. This is the situation regarding Jam Sessions, a program for DS that began its life as "Sing and Play DS Guitar M-06" by Japanese developers Plato. The program was picked up by Ubisoft, who made significant improvements before releasing it in America and Europe.
