Retoree started to have flashbacks when she was first scouted by Banded Rocking Records.
Later while in her room, Cyan gets an explanation from Strawberry Heart that a Battle of the Bands was where two bands compete, and the fans that are watching it vote for their favourite band. The winner will get sound dollars and a chance to level up their Melodisian Stones.
Before the Battle, Cyan, Retoree, Chu Chu and Moa, had their mix of feelings for it but all ended up with their own resolutions which was to win. Cyan after hearing what Strawberry Heart said, thought about the idea of something more than winning the opponent.
After witnessing the show that Cristicrista put on during rehersal, Plasmagica was devastated with no hope of winning against them. Cyan cheers them up by saying the improvements on the song that could be made. They all ended up with suggestions on their own. They regained their confidence and played the improved song.
