Wii Karaoke U by JOYSOUND (also known as Karaoke Joysound for Wii U) is a karaoke game developed by TOSE and published by Nintendo for the Wii U. It is a spiritual successor to the Wii title Karaoke Joysound. The game itself is free, but to sing songs, you need to purchase a ticket from the eShop and remain connected to the internet. The service ended in March 31, 2017 for Europe.
The service operates on a ticket system. Users could purchase tickets to the length of the session they wanted from as short as 1 hour to a full day. Users could also buy a 30-day ticket if they wanted to use the service all month long. While the ticket was active, the users can select any song active on the service. The songs differed between regions.
Like a Karaoke room, the users select the songs on the Wii U GamePad and designate the singer. The singer's Mii appears on the screen when their song is up. As the song is playing, the top of the screen displays a music staff with correct relative notes to the song. The player sings trying to match this into the microphone. The Mii sings and dances on the rest of the screen with the lyrics in the middle. The game will output the player's voice as they sing.
