The game was free to download but required the purchase of a karaoke ticket to sing songs, as well as an internet connection.

Similarly, the stage can be customized to add band members, choreographed dancers, pyrotechnics, among other additions.

[8] Shortly after its launch in Europe, Nintendo Life broke a story revealing that Wii Karaoke U did not censor any of the songs in the Joysound library.

Italian Eurogamer gave the game 7/10, citing that the heart of the experience was polished, but notes that the lack of stage customization options and a superficial management of the social components of karaoke hold it back.
