Hmmm...
I'm having difficulty determining if by troll you reffered either to the little blue/green monsters or if the song itself was a troll! ;)
The song itself was kind of hard to the ears, wich was probably the point, and I'm pretty sure you didn't let some wrong notes for nothing, LOL.
At certain points, the song sounded more like drum n' bass, with the gorey sounds and all. Not sure what they were, but I don't really want to know...
Anyways, nice christmas carol, if you must know it's one of my favorite!
If I don't review another one of your songs, Merry Christmas!
Cheers,
