mode, "Way Off" becomes "Way Early" and "Way Late" respectively; in other modes, the dash system still applies. "Stretch Jumps" have been included in double play, a jump that requires a player to hit two panels simultaneously that are farther away from each other than normal jumps, such as 1PU+2PD or 1PL+2PL. Songs In the Groove 2 includes more than 60 new songs in addition to the entire songlist from the previous version, In the Groove. The sequel includes new songs from established artists like ZiGZaG, Kid Whatever, Inspector K, Nina, Digital Explosion, and Machinae Supremacy. It also introduces songs from newcomers like Tekno Dred, Affinity, Hybrid, Lynn, and Onyx. As with the original game, several artists that have released songs for Dance Dance Revolution games appear on ITG2. These include Bambee, Missing Heart, Spacekats (known as Bus Stop in DDR, with the exclusion of one member), Ni-Ni, Triple J, E-ROTIC and Lynn (Papaya in DDR). In fact, three songs appear on ITG2 that have been on Dance Dance Revolution games, though with different step charts: Typical Tropical and Bumble Bee from Bambee and Sunshine (originally Follow The Sun) from Triple J. Of note, Wanna Do ~Hardhouse Mix~ is the only song in ITG to have a dedicated music video in-game, as it also serves as the theme song for the game.
