So whats your ONE favorite Opeth song?

I'll never name one favorite because I stand by so many as brilliant. Saying one is better then the other would be like turning your back on something special. Maybe my first can be my fave if a gun was put to my head. Which would be Forest of OcFuckingtober, there!
 
I decided to look back and read some of the posts on this and fuck!! I can't believe so many people like BWP...thats an awesome fuckin song!! But When is my favorite that one melody in there is just divine and makes me wanna cry and I'm sure you all know wtf I'm talking about. It's When for sure. Sorry, I'm so full of shit.
