"Born Of The Night" is for sure my favorite. I even took the Forbidden Crypts song name for my website Home Page Name, and use it in many places as my user name. That song is embedded in my Forbidden Crypts page too. It is my favorite of all of their songs as well.
I even have an MS Listening Page that was approved by one of MS's Representatives. She emailed me one time, and said it was ok as long as I blocked the songs from being downloadable.
