I tried getting the actual tabs for this song, but was disappointed when my searches
returned only chord progressions that were close, but not quite as dissonant and beautiful
as the actual chords of the song. So, after listening to the song more times that I can 
count, here is the actual guitar part. The guitar part was constructed by matching notes
on the piano (and sounds like the song), so I believe it is authentic.

PLEASE NOTE IRREGULAR TUNING (credit to some random person who commented on the video on youtube!)

The line:
1/2-2-1/2-2/2-/2---1-1/2-2-1/2-2/2-/2---0-
I know I said to slide, but I usually just put down my middle finger onto the second
fret instead of sliding my index. The notation 2/2 mean after the first 2 on the beat play
a quick first fret and quickly press back down on fret two. This is like the second /2. 
Quickly play the first fret before pressing the second.

X in the tablature means that I usually just graze the string with my ring finger
(playing the D string lowest in pitch). This way you can strum all six strings but that one
will be inaudible.

d:Stroke downward, u: upward, p: play with thumb before continuing down stroke. These
are just included so that you get a sense of the strum pattern.

Enjoy!
