Official description of songbattle.io:
songbattle.io is the new favourite browser game for every music loving Twitch Streamer or friend group! Engage with your Twitch community or friends in exciting battles competing your favourite songs against each other.
Start your songbattle now and invite your friends or Twitch viewers to submit songs, which are being pitted against each other in a 1-VS-1 tournament.
On the right you can see an example how your game could look like! On the computer screen you can see the songbattle game being started by a Twitch streamer. The participant (in this case a Twitch viewer on a mobile device) sends in his favourite songs. Of course you can choose your devices at your leisure. If the host lets the viewers decide, they can vote directly in the streams chat. The song with the most votes enters the next round.
Who will win the song competition at the end?
