Code Lyoko - Season 1 - Eps 18: Killer Music
A new rock song Odd downloads sends him into a coma, and the same song is passed through the school. XANA's new beat is the cause, and he can broadcast it anywhere. The hospital is full to bursting with cases, and Odd's heart gets weaker with every beat it makes. But when the tune starts playing in the factory, will the crew learn that music can do more than just soothe the soul? And, will Aelita be able to save the crew? It's all up to a leap of faith...
