Killer Music

From Code Lyoko Wiki

In killer music, Odd is playing loud music, dancing a round and singing. Ulrich is trying to study and is sick of odd, so he goes to sleep over in Jeremie's room. Meanwhile, XANA takes over the music stations and everyone who listens to the music is sent into a coma. Odd is the first one to do so, making Ulrich feel bad about yelling at him before. Sissi is the second one to fall into a coma, then the nurse, then every one. In lyoko, Aelita can't find the tower and the music soon comes to Jeremie and Ulrich. As soon as aelita finds the tower, Jeremie has just enough energy left to launch a return to the past.
