the full song is only 2:07, i think its just misscomunication, rubix wanna get longer showcase that's why no one expected, so he ask to repeat the song. rubix total showcase is the same twice using the same song, cuz i know the song
I’m pretty sure they just wanted more from rubix so he repeated the track to give them what they want, rubix just stops suddenly at 3:27 to end the performance it’s a very normal thing for him to stop and walk off at the end of his round
