If you want me to explain in detail what I believe to be the reason for them showing up so early in Greatest Hits levels, I can, but long story short, it's to do with the way jams work in Greatest Hits. I curious for this..Why do you think the sheer appearance of Hair Metals depend on the jam? They can very well not appear at all during Rock. that is also a possibility. Every time they appear unusually early (such as pre-first-flag), the music changes to Metal in the same wave they appear. My guess is that whenever the music changes to a certain jam, at least one zombie affected by that jam has to appear in the same wave, even if that zombie doesn't usually appear that early in a level.

This therefore means that if the game decides to play the Metal Jam early on, Metal Gargs appear early on. So far I've seen nothing that disproves this theory and it seems quite likely based on all available information I have.
