X is a common symbol for multiplication. Example: 5x3=15. Fold is another way to say multiplication. Example: Our crop yield this year is tenfold of last! That means the speaker was able to harvest ten times as many crops.
I think Avenged Sevenfold sucks, but I wanted to point that out.
I've been taught to use "*" as the multiplication symbol, rather than X, because X can be misconstrued in algebra.

The Beast And The Harlot ;)
Highly overrated. Only good part is the tap solo during the chorus.
