Music will always be DDR's most important element since without it, you're just stepping on arrows and looking like a jackass. Ultramix 3 offers around 70 songs and features DDR favorites like "Butterfly", "Crazy in Love" and "Captain Jack" as well as new tunes from the Black Eyed Peas, Run D.M.C., They Might Be Giants and Good Charlotte. Overall, the selection of tunes is great and should offer something for everyone. You won't always get to dance to the songs you want since some force songs on you, though some modes will let you choose if you have a few favorites. Downloadable song packs are also available over Live, though they come with a small fee.
As a bit of an added bonus, a Jukebox mode is available that allows you to create a playlist of songs to listen to without having to dance, which is good if you want some DDR-styled background noise and don't own any of the game soundtracks.
Ultramix 3 retains the series' low-key approach to visuals. Arrows are obviously the most prominent aspect, while backgrounds are filled mostly with either simple, cel-shaded dancers or videos from the song's artists. There's nothing here to get overly excited about, yet at the same time, it probably isn't that good of an idea to pay that much attention to the backgrounds anyway.
