There were three songs we got to hear them play and only two of them were new. I think the first one was Yui's "Ichi ni san shi Go-han" song. After I heard that song I thought they were going to play Mio's Raccoon's Love Shower, but they didn't... The second one was Fuwa Fuwa Time was heard in the background in one scene and the last song was U&I. But those were the only songs heard in this episode. They could've played more and KyoAni just decided not to show them. But I was really hoping to hear hear Honey Sweet Tea Time.
