Cytun or guitar hero like game on pc, asian pop, forgot name?

Argh! I was Watching a twitch stream (league) and saw whoever it was playing it in between queues. The gameplay was identical to cytun but the layout and art was totally different. I stumbled on cytun by accident and now I want to find this other game sooooo bad! It was bright pink and you hit little bubbles to the beat of what sounded like anime songs. It was adorable, but looked pretty hard too. Sound familiar? Please and thank you!
