ABBA: You Can Dance is a video game for the Wii, developed by Ubisoft. It was released on November 15, 2011 in North America, November 24, 2011 in Australia and November 25, 2011 in Europe. The game is a spin-off of the Just Dance series. The game includes a "Karaoke Mode" which allows 2 players to sing via USB microphones, unfortunately not all of the songs are singable.

Karaoke Mode
This game accept two USB microphones that can be used in karaoke mode. However, Dolphin doesn't emulate Wii USB interface, and Karaoke Mode isn't playable.

Audio issues
When using DSP HLE, at the beginning of a song the game keeps repeating the last played SFX among the music. The current workaround is using DSP LLE.
