I can't believe this thread got resurrected.
well, in my religions class this last semester we were told to bring in a religious song to display to the class. I took the M PV and presented it as a religious allegory. (For obvious reasons) Talking about the meaning and the setting of the church and what Christianity is in Japan. Everyone, including the prof, was REALLY interested so that made me excited. I didn't convert anybody but people were really impressed with the song/video. A girl afterwards even told me she thought it was really cool and that Ayu was hot.
