^Because the chorus "...you're better of dead than fucking with me..." is tricky to play, and he has to play and sing over it.
I don't know but I have the feeling they may be playing Children Of Bodom this European tour at least. It's been a long time since they last played it (I don't think Roope's played it) and they try to change the setlist a bit each tour, you know, not always play the same songs of each album
I don't want to see Sixpounder and HCD go anywhere tho, I'll be very sad if they don't play those two. From AYDY I myself would play LDB and then IYF or WNGF, and from Blooddrunk the title track and SPFTD. I also think they shouldn't play more than one slow song, just one around the middle of the set to get a breather, but not two, so I'd rotate, and this time around instead of ADK or BFH I'd like to see them play ETID.
