Evolved Series

The Evolved series consist of hard songs in DDR that are notorious for being random. Their gimmick is that one song, simply titled "(City) evolved" is available on the song wheel, however, in gameplay it actually randomly loads one of three stepcharts, some of which feature BPM changes not seen on the default one, or songs that sound different in some sections. These songs originally debuted on the Hottest Party series, the third one started appearing on other consoles and even in the arcade versions.
To date, there have been 5 songs in the series, composed by a variety of Bemani artists.

==Trivia==
*The concept of random songs being loaded is not entirely new. In DanceDanceRevolution Supernova 2, Sunkiss Drop, was available in Alison Side (English) and jun side (Japanese). The Alison side plays by default on the song wheel, but the player may end up playing the jun version. Opening folders in a specific order in the PS2 versions enabled players to play the jun side 100% of the time. There are no stepchart variations between the two and this gimmick was dropped in X2.
