Most of it is just guesswork so mistakes might occur, 
mostly at drums. I concentrated mostly on the guitars 
and tried to make them sound at least close to the 
original. When the song climaxes for the second time 
an octave pedal might come in handy since all notes 
of the lead sound simultaneously one octave higher 
than what they are actually played. The tuning is 
completely messed up by the band but I did some 
research. So that's all I suppose...
