I understood the lyrics, having read the book, I just think that any lyric that includes Kwizatz Haderach and Gom Jabbar is pretty damn silly. I otherwise do like the song, though.
Back to Dio: The video for Mystery was on TV the other night, and my 5-year-old son asked me to replay it 3-4 more times (gotta love TiVo). Not my favorite Dio song, but I was pleased nonetheless. If I had to rank my five favorite Dio songs, it would be an imperfect list, as it would be drawn entirely from the first three albums, as I'm not as familiar with the others. Still, they'd be:
1. Don't Talk To Strangers
2. Egypt
3. Holy Diver
4. Rainbow in the Dark (I know, I know, I'm lame)
5. Sacred Heart
