Twitch stated that they made the decision to close the game to "invest in broader tools and music services.

"[1] In October 2018 during TwitchCon, Twitch announced that they'd developed a karaoke video game in collaboration with Harmonix.

[2] During the opening keynote, Twitch CEO Emmett Shear stated, "We believe in a new category of game that’s made to be streamed, where the audience isn’t just nice to have, they’re crucial to the experience, where the driver’s seat is big enough for your whole community.

This allowed stream audiences to interact in various ways, such as voting on singing challenges for the broadcaster to attempt, along with sending in virtual ovations if they enjoyed the performance.
