i'm not too confident in this, but it sounds close

After the last riffs the rhythm goes back to normal and you repeat the song 
again..you should go through the song atleast twice, then start one more time 
but never finish it. Remember, theres lots of space between all the notes and 
the song is very slow paced for a creepy sound.
