Well as we may know, Halloween Haunt is coming soon, which means the season will be down in a few months):

BUT why not think of some cool or "spookey" songs for Halloween Haunt..

I would say maybe something like "Scream" by Avenged Sevenfold, What I've Done by Linkin Park...

So let's get some ideas rollin'!

My favorite song I have ever played in Orchestrations. I love it. I listen to it every Halloween However, it is a little "lite" for something like Halloween Haunt, so I would say just for Halloween in general.
For those of you that don't know; the song is about skeletons coming to life and dancing on the one night they are allowed to leave their graves (notice the 12 notes on the down beat are a clock tower). Sadly, at 6:19 the rooster caws, telling the skeletons that their time of playing is over. They slowly going back to their graves, but not without dancing a little more first Enjoy si vous plait!

No Quarter-Led Zeppelin (My all-time favorite song)

Fallout 3 theme(if you want a more classical feel)

I would say maybe something like "Scream" by Avenged Sevenfold.

This would be perfect.
